Good day! Today we will be tackling the basics of crew skills and perks. I have seen countless of players, veterans and newbies struggling which perk or skill should i take and I keep hearing different interpretation of 1 skills/perk from different people. Now lets begin with the basics. Every tank in World of Tanks needs a crew to operate your steel monstrosity. Crew member has a Major Qualification, this is the role that they fullfil in the tank. Namely the: Commander, Gunner, Driver and Loader. Depending on the tank, some crew members has more than 1 major qualification(i.e The Russian IS4 Heavy Tank, the commander is also the radioman.) and some tanks has more than 1 crew member with a specific Major Qualification (i.e the Pz.Kpfw. B2 740 (f) which has two radioman or the E100 which has 2 Loaders) Just like any vehicle in World of Tanks, the crew gains experience points every battle. Crew members accumulate experience which increases their skill level and proficiency of their major qualification, which is represented as percentage. How the proficiency of crew members contribute to the overall combat effectiveness/performance of your tank. Commander:
- View Range.
- 11% bonus to all crew major qualifications.
Gunner:
- Aim Time
- Accuracy
- Turret Traverse
Diver:
- Maneuver in specific terrain
- Traverse speed
- Acceleration
Radio Operator:
- Radio Range
Loader:
- Reload time
If a crew member is knocked out, corresponding performance is reduced. Once a crew member reaches 100% proficiency, they are now able to learn “crew skills“. Crew skills can be used to further increase the performance of the tank.Some Crew skills/perks only available to certain kinds of crew. 
Skills and Perks work differently. A skill take effect as soon as you start training your crew with it. While a perk only takes effect once it has reached 100%.
“The Effective Training Level of the Common Skills, (Repairs, Firefighting, and Camouflage) are averaged across all crew members. If more than one crew member in a vehicles have the same Common Skills, then the average of their Training Levels is used to determine their joint performance in the Common Skills. For example, for a vehicle with a crew of 4 and two of them are trained in Repairs, one to a level of 60% and one to a level of 100%, then the Effective Training Level for the Repairs Skill for the vehicle is (100+60+0+0)/4=40% and this value will apply in battle mechanics and vehicle perforance calculations.”
The crew skill and perks description in game is fairly accurate but lacks detail. Here is the list of skills per crew and in the words of WarGaming itself (cannot paraphrase the skills and perks, it will only lead to confusion):
Hope you’ve digested at least 70% of those skills and perks descriptions. Now for the “Recommended” crew skills and perks per tank class. The following are based from my (IGN: _Robin and my sister _Lust) personal experience with over 34,000 battles, Pro gaming expirience and practically owning all tanks in game,except for arty ( I have no future with SPGs) and the JPzE100 line (but Im working on it :P). The crew skills of Medium,Heavy and Tank Destroyers are almost identical, except in medium tanks you focus a bit more on vision and camouflage, earlier than the Heavy Tank. And as for the Tank Destroyers, it all depends on what you do with your TDs, I personally use them like a turretless Medium tank(except for the slow ones), so I prefer repairs over camouflage. But if you’re a classic TD player, camo skill is the way to go. First skills/perks:
- Sixth sense is a mandatory skill for any tank.
- REPAIRS on ALL crew members. I cannot stress how important this skill is. Take for example you got detracted its 5 seconds with full repair skills vs 12 seconds without repair (depends on the tank but this is the average repair time).
Second skill/perks:
- Repair on commander.
- Camouflage(Medium Tanks) for the rest of the crew
- What I do with my Heavies is, when my 2nd skill (doesn’t matter what) reaches 50% I drop all the skills and retrain my crew using just 10,000 credits with FULL Brothers in arms, giving me an instant 100% on perk.Then set the second skill Commander: Sixth sense. The rest: Repairs
Third skills/perk and beyond:
- Commander: you can train him with camouflage to complete the set(Medium Tanks)/Recon
- Commander: Repairs (Heavy Tank)/Jack of all trades
- Loader: Safe stowage/adrenaline rush/Intuition
- Driver: Clutch braking/smooth ride/off road driving —Controlled impact on E50M,Amx 50B and similar tanks are a must if you have the urge to ram other tanks!—
- Gunner: Snapshot/Deadeye/Armorer
- Radio Operator: Signal boosting/Signal boosting
For Light Tanks: 1st skill/perk:
- Commander: Sixth sense
- Camouflage for the rest of the crew.
2nd skill/perk
- Commander: Camouflage
- Gunner: Designated target
- Driver: Off-road driving
- Loader: Safe Stowage
- Radio Operator: Situational awareness(but in most light tanks the commander is also the radio operator)
3rd skills/perks and beyond.
- Commander: Recon
- Gunner: snap shot/deadeye
- Driver: smooth ride/clutch breaking
- Loader: Adrenaline rush/intuition
- Radio Operator: call for vengance/signal boosting/relaying (but in most light tanks the commander is also the radio operator)
