Quick Glossary (So the Rest Makes Sense)
World of Tanks uses some terms that sound similar but mean very different things. Here are the ones you’ll see in perk reset and Crew Book screens:
- Crew Member: One person in your crew (Commander, Gunner, Driver, Loader, Radio Operator, depending on tank).
- Major Qualification: The crew member’s main role in the vehicle (their core job).
- Perks: Trainable improvements your crew member earns using Crew XP.
- Perk Experience (Total Perk XP): The total “pool” of experience your crew member has accumulated for perk training. This is what resets can reduce or preserve.
- Reset: A way to change which perks are selected while keeping some (or all) of the perk experience.
- Crew Book: An item that adds a fixed amount of Crew XP to one crew member or the entire crew of a selected vehicle, depending on the book type.
- Complete Crew: The vehicle has every required crew slot filled. Many books require this.
- Specialization Matches Vehicle: The crew is trained/specialized for that vehicle (Premium vehicles often have more flexibility than researchable vehicles).
- Quick Training: A garage area where you can speed up training using resources like Crew Books and other training materials.
If you keep those ideas in mind, everything else becomes much easier.
Where to Find Perk Reset (And Why Players Miss It)
Perk reset is not a “global account button.” It is tied to each crew member, and you typically reach it through that crew member’s profile.
A simple way to think about the UI flow:
- Open the crew member’s profile
- Navigate to the perks area
- Look for a Reset option
If you only ever manage crews through the tank carousel and never open crew profiles, perk reset can feel hidden. The moment you start opening crew profiles as a habit, reset becomes a normal tool instead of a scary one.
What a Perk Reset Actually Does
A perk reset does two things:
- It clears or changes which perks are currently selected for that crew member.
- It returns perk experience to a usable pool so you can reassign it into different perks.
The important detail is this:
A reset is not just “switch perks.” It’s “switch perks with a rule about how much experience you keep.”
That experience rule is the entire point of the different reset options.
The “First Reset Is Free” Rule
For perk reset, World of Tanks uses a helpful base rule:
- The first reset for any crew member is free.
This is a big deal because it means every crew member gets at least one “no-cost correction.” It also encourages learning and experimenting—without making you feel punished for your first decision.
After the first free reset, you get multiple reset options with different costs and different experience outcomes.
Perk Reset Options Explained
After a crew member’s first free reset is used, the game presents a set of reset choices. These options are designed for different priorities: free but losing more XP, cheap with small XP loss, or more expensive with no XP loss.
Here are the standard reset methods you will typically see, and what each one does:
- Rapid CoursesCost: free
- Effect: the crew member’s total perk experience is reduced by 20%
- Meaning: you can reset without paying credits, but you lose a meaningful chunk of accumulated perk progress.
- Regimental SchoolCost: 20,000 credits
- Effect: the crew member’s total perk experience is reduced by 10%
- Meaning: a small credit cost helps you keep more of what you earned compared to the free option.
- Tank AcademyCost: 100,000 credits
- Effect: total perk experience remains unchanged
- Meaning: you can freely change perks without losing any of the accumulated perk experience.
- Retraining (Retraining Order)Cost: requires a Retraining Order item
- Effect: does not change the total perk experience
- Meaning: this is a “token-style” no-loss reset.
The big takeaway:
- Rapid Courses and Regimental School are “pay with experience.”
- Tank Academy and Retraining Order are “pay with credits or items” while keeping all experience.
What “Reduced by 20% or 10%” Means in Real Terms
When the game says “total perk experience is reduced by 20%,” it means the entire pool of perk XP that crew member has earned gets cut.
A simple example with clear numbers:
- If a crew member has 1,000,000 total perk XP
- Rapid Courses (−20%) reduces it to 800,000 total perk XP
- Regimental School (−10%) reduces it to 900,000 total perk XP
- Tank Academy keeps it at 1,000,000 total perk XP
This matters more than it sounds, because perk progress is not linear in “how it feels.” Losing 10–20% can:
- drop you below a perk threshold you were about to complete
- reduce your total number of completed perks
- make a deep crew feel noticeably “less developed” after the reset
That’s why it’s important to treat Rapid Courses as a convenience option, not a default habit.
Does a Reset Remove Completed Perks?
Reset behavior can feel confusing because you see two things at once:
- perks being changed/cleared
- total perk experience being preserved or reduced
A reset does not “delete” perks as a concept; it removes your current perk selections and returns the crew member’s progress into a usable pool. Then you reassign it.
If the reset reduces total perk experience (like Rapid Courses or Regimental School), that pool becomes smaller—so you may not be able to reselect the same number of perks you had before.
The practical interpretation:
- No-loss resets let you rebuild your perk choices without shrinking your total progress.
- Loss resets force you to rebuild with a smaller budget.
When Each Reset Option Is Most Appropriate
This page isn’t about forcing one “correct” choice for everyone. Instead, here’s the safest way to think about reset options based on what you’re trying to protect:
- If the crew member is a long-term project with a lot of perk progress, a no-loss reset is the safest way to avoid regret later.
- If the crew member is new, temporary, or has minimal perk progress, the “loss” options hurt less because there’s less total experience to lose.
- If you are resetting due to an update that introduced new perks or changed perk behavior, no-loss resets are often more comfortable because they let you adapt without shrinking what you earned.
In other words: the deeper the crew, the more valuable XP preservation becomes.
Reset Timing and Update “Grace Periods”
World of Tanks periodically introduces major crew updates (new perks, perk reworks, UI changes). When this happens, the game sometimes provides:
- a grace window where you can reset freely or more flexibly, so you can adjust without pressure
- additional free reset opportunities so players can adapt to the new system
If you return after a break, this is why you may see unusual reset availability for a limited time. The best habit is simple:
- When a crew update drops, open your crew screens and read what reset options are currently offered. Don’t assume it’s the same as last year.
Retraining Orders: What They Are in Plain Language
A Retraining Order is an item that acts like a “special currency” for certain crew operations. When you use it for a reset:
- you can change perks without reducing total perk experience
- you avoid spending credits for the Tank Academy option
If you see a Retraining Order in your rewards and you don’t know what to do with it, treat it as:
- “a no-loss reset token I can use later when I want flexibility.”
The Safest Reset Routine (Avoiding Misclicks and Regret)
Perk resets are reversible only in the sense that you can reset again—often at another cost. To avoid wasting credits or experience, use this simple routine every time:
- Step 1: Open the correct crew member profile and confirm their name/role.
- Step 2: Check how much perk progress they currently have (so you understand what you’re protecting).
- Step 3: Decide whether you’re willing to lose experience today (Rapid/Regimental) or not (Tank Academy/Retraining).
- Step 4: Reset, then immediately reassign perks deliberately (don’t leave them “empty” and forget).
- Step 5: If you’re testing new perk combinations after an update, write a quick note for yourself (even a phone note) so you remember what you changed and why.
This routine sounds basic, but it prevents the #1 mistake: resetting the wrong crew member or choosing the wrong reset cost in a hurry.
What Crew Books Are (And Why They Feel So Powerful)
Crew Books are items that instantly add Crew XP. Think of them as “training packages” you apply in the garage.
Crew Books exist for three reasons:
- to help new players catch up on crew progression without endless grinding
- to let long-term players invest credits into crew growth
- to make events and missions feel rewarding with meaningful progression items
The key is understanding that not all Crew Books are equal. Some apply to a whole crew. Some apply to one crew member. Some are locked to a nation. Some are universal.
Where Crew Books Are Stored
Crew Books are stored in your Depot, in a dedicated Crew Books section. The game also provides filters so you can find the exact book type you want (nation books, universal books, personal books).
This is important because many players “forget” they have Crew Books simply because they never open the Depot filters. If you want Crew Books to actually help you, checking your Depot occasionally is a smart habit.
The Seven Crew Book Types (And Exactly What They Give)
World of Tanks currently presents seven main Crew Book types. Each has a defined XP amount and a defined target.
Here they are in plain language:
- Training BookletApplied to: the whole crew
- XP granted: 20,000 XP to each crew member
- Nation: tied to a specific nation (used on vehicles of that nation)
- Typical sources: events and special rewards
- Training GuideApplied to: the whole crew
- XP granted: 100,000 XP to each crew member
- Nation: tied to a specific nation
- Typical sources: events
- Training ManualApplied to: the whole crew
- XP granted: 250,000 XP to each crew member
- Nation: tied to a specific nation
- Typical sources: can be purchased for 2,000,000 credits (per manual)
- Universal BookletApplied to: the whole crew
- XP granted: 20,000 XP to each crew member
- Nation: universal (not nation-locked)
- Typical sources: rewards (commonly through mission-related systems)
- Universal GuideApplied to: the whole crew
- XP granted: 100,000 XP to each crew member
- Nation: universal
- Typical sources: rewards (commonly through mission-related systems)
- Universal ManualApplied to: the whole crew
- XP granted: 250,000 XP to each crew member
- Nation: universal
- Typical sources: rewards (commonly through mission-related systems)
- Personal Training ManualApplied to: one selected crew member
- XP granted: 850,000 XP to that crew member
- Nation: works for any nation
- Special note: the major qualification level requirement does not matter for using it
That’s the “what.” Next, you need the “rules.”
Crew Book Rules: Conditions That Must Be Met
Most “why can’t I use this Crew Book?” problems happen because a condition isn’t satisfied. For books applied to the whole crew, the common requirements include:
- The vehicle must have a complete crew.
- The major qualification level of all crew members must be at least 100% (this is based on their real training level, not temporary bonuses).
- The crew specialization typically must correspond to the vehicle (Premium vehicles have special flexibility rules).
- For nation-tied books, the vehicle/crew must match that nation.
If any of those fail, the book may be greyed out or unusable in the screen you’re on.
Personal Training Manuals are much more flexible because they target one crew member and do not require the major qualification level condition.
Nation Books vs Universal Books (The Simplest Way to Remember)
Use this mental shortcut:
- Training = nation-tied (Training Booklet/Guide/Manual)
- Universal = works broadly (Universal Booklet/Guide/Manual)
This matters because nation books are often easier to waste if you don’t pay attention. If you apply a nation book to the wrong nation’s context, it simply won’t apply—or you’ll be forced to change context until it matches.
Universal books reduce friction. They’re easier to use across your account.
“Applied to the Whole Crew” Means the Value Multiplies
When a book says “provides each crew member with 250,000 XP,” that is per crew member.
Example:
- You apply a 250,000 XP whole-crew book to a tank with a 4-person crew.
- Each crew member gets 250,000 XP.
- Total XP distributed across the crew is 1,000,000 XP.
This is why whole-crew books can feel extremely powerful: the effect scales with crew size.
It’s also why you should be deliberate. Applying whole-crew books to a crew you won’t keep long-term can feel wasteful later.
How to Apply Crew Books
There are two common ways to apply Crew Books:
- From the Depot’s Crew Books tab (where you can filter and select what to use)
- From Crew Management / Quick Training screens (where the game helps you apply training items and even estimate how many are needed for a target)
A safe habit:
- Before clicking “use,” confirm the selected vehicle and the crew shown on the screen are the ones you intend to train.
That one check prevents most misclick regrets.
Buying Training Manuals for Credits (What That Actually Means)
Training Manuals (the 250,000 XP nation manuals) can be purchased for credits:
- Cost: 2,000,000 credits per manual
- Effect: adds 250,000 XP to each crew member of the selected vehicle (whole crew)
The game also offers a “how many do I need” style estimator in the Quick Training interface, showing you how many manuals would be required to reach a target perk count and whether there will be extra XP beyond the exact target.
Important mindset:
- Buying manuals is a credit investment. It’s a garage economy decision, not a battle decision.
If you are careful with it, it can be one of the cleanest ways to convert credits into long-term account comfort.
What Happens If You “Overtrain” (Extra XP Beyond Your Target)
Sometimes you apply a Crew Book and it gives more XP than you expected for the next perk threshold.
That extra XP is not “broken.” It simply means:
- your crew’s perk XP pool is now ahead of the exact line you were aiming for
- future perk progress starts from that higher point
This is why the training interface may show a symbol that indicates “you’ll receive more XP than needed for your chosen target.” It’s not warning you of loss. It’s warning you of overshooting the target line.
Post-Progression and the Universal Guide Reward
World of Tanks also includes a “post-progression” concept:
- When a crew member fully trains a large set of major qualification perks (commonly described as six), they continue earning Crew XP.
- For every 100,000 XP earned in post-progression, you receive a Universal Guide that can train other crews.
This is designed to ensure that continued play still creates account value even after a crew becomes very developed.
Practical habit:
- If you’re a long-term player, check your Crew Books inventory occasionally to see whether post-progression rewards accumulated and need to be claimed or used.
A Clean “Don’t Waste Crew Books” Decision Framework
This is not about “the best meta.” It’s about protecting your time and resources.
Ask three questions before using a Crew Book:
- Is this a long-term crew?
- If the crew will stay with you for months, investing books feels better long-term.
- Is this the right book type for my situation?
- Whole-crew books scale with crew size, so they’re a bigger “commitment.” Personal training manuals are more surgical.
- Do I meet the conditions so the book applies cleanly?
- Make sure the crew is complete and the major qualification is at 100% if required.
If you do those three checks, you will avoid most wasted book stories.
Perk Reset and Crew Books Together: The Smart Order
Perk resets and Crew Books interact emotionally more than mechanically:
- You don’t want to pump XP into a crew and then realize you hate the perk layout and need to reset.
- You also don’t want to reset, lose XP with a cheap option, and then feel forced to “repair” the loss using Crew Books.
A clean, low-regret order is:
- confirm your perk layout first (reset if needed)
- then apply Crew Books to build progress on top of a layout you’re comfortable with
This keeps your economy and your crew plan aligned.
Common Mistakes Players Make With Resets and Crew Books
These are the most frequent mistakes that create regret:
- Resetting the wrong crew member because you didn’t verify the profile
- Choosing Rapid Courses repeatedly on a highly developed crew and slowly shrinking months of progress
- Forgetting that only the first reset is free and clicking reset casually later
- Trying to use a whole-crew book on an incomplete crew (it won’t apply)
- Trying to use books before major qualification is at 100% (for books that require it)
- Using nation-tied books without realizing they’re nation-tied
- Using whole-crew books on short-term crews you will replace soon
- Forgetting Crew Books are stored in the Depot and letting them sit unused for months
Fixing these doesn’t require more skill—just a better garage routine.
A Simple Weekly Routine for Crew Progress
If you want a routine that keeps your crews growing without confusion, do this once per week:
- Check your Depot Crew Books tab and note what you have.
- Identify one or two long-term crews you’re building.
- If you’re unhappy with perk layouts, do resets first (and choose a reset option intentionally).
- Apply Crew Books only after you’re comfortable with the perk direction.
- Keep credits in mind: Training Manuals cost a lot, so treat them like planned purchases.
This routine keeps crew progress steady and reduces “random spending.”
BoostRoom: Crew Management That Feels Simple, Not Stressful
Perk reset screens and Crew Books are powerful, but the game doesn’t always teach them clearly. BoostRoom helps players turn crew management into a simple system:
- Understanding which reset option matches your goal (free vs credit vs token)
- Setting up a clean “reset first, train second” routine that avoids waste
- Organizing your Depot and Barracks so you always find the right crews and books quickly
- Building a long-term crew plan that fits your schedule and your garage goals
If you’ve been sitting on Crew Books because you’re afraid of using them wrong, BoostRoom helps you stop guessing.
BoostRoom: Save Credits and Protect Your Progress
A lot of “slow progression” is actually “accidental waste”:
- XP loss from repeated low-cost resets
- big Crew Books used on short-term crews
- manuals purchased impulsively instead of planned
- cluttered Barracks that causes wrong retrains or wrong resets
BoostRoom focuses on keeping your account progress predictable. The outcome is simple: your credits feel steadier, your crews feel more consistent, and you spend fewer resources fixing mistakes.
FAQ
Do I really get a free perk reset?
Yes. The first reset for each crew member is free. After that, the game offers additional reset options with different costs and XP preservation rules.
What’s the difference between Rapid Courses and Regimental School?
Rapid Courses is free but reduces total perk experience by 20%. Regimental School costs 20,000 credits but reduces total perk experience by only 10%.
What does Tank Academy do?
Tank Academy is a no-loss reset option that costs 100,000 credits and keeps total perk experience unchanged.
What is a Retraining Order reset?
It’s a no-loss reset that requires a Retraining Order item instead of credits, and it keeps total perk experience unchanged.
Why can’t I use a Crew Book on my tank?
Most whole-crew books require a complete crew, 100% major qualification, and (in many cases) specialization matching the vehicle. Nation-tied books also require the vehicle/crew to match that nation.
What’s the difference between Training and Universal Crew Books?
Training books are nation-tied (Training Booklet/Guide/Manual). Universal books are designed to be used broadly across nations (Universal Booklet/Guide/Manual).
