My Guide to Skills

In this guide I will look at the skills that each crew member has and give suggestions on what to use

If two crew members with the same qualification have a perk (or skill), then the highest researched of the two is the only one that is effective. Thus, if you have 2 loaders or radio operators it is better to train different skills or perks

At the bottom you will see my recommended setup

The skills:-

1,  Repair
This skill accelerates repairs to damaged modules, Recommended for: Heavies, Tank Destroyers, Mediums and lights which want to keep on move

2, Camouflage
This skill reduces vehicle visibility, Recommended for: All tanks

3, Firefighting
This skill enhances fire fighting abilities, Recommended for: German Heavies, Russian Heavies & Mediums

4, Brothers in Arms
This perk improves major qualifications and all skills and perks for the entire crew. The perk comes into effect after it reaches 100% for the entire crew. The perk is more effective when combined with Improved Ventilation, Extra Combat Rations, Chocolate, Case of Cola, and Strong Coffee.

Recommended for: Lights, Mediums, Tank Destroyers & slow Heavies

11, Off-Road Driving
This skill reduces ground resistance when driving on soft and moderately soft terrain. The effect increases with skill level. Lower ground resistance increases vehicle maneuverability and acceleration. The skill is more effective when combined with Additional Grousers.

12, Smooth Ride

19, Safe Stowage

21, Adrenaline Rush

This perk enables a Radio Operator who survived the destruction of his vehicle to report enemy positions for another two seconds. Call for Vengeance comes into effect after it reaches 100%. If two Radio Operators have the perk, the effect is not cumulative.


Don't blindly follow my examples below before taking a perk read up on its usage for example there is no point in taking Snap Shot for a tank that has no turret

So as far as I can tell you are only able to get 3 perks (least everything I read I have never seen more than 3), so my recommended setups are :-

Commander
1, Mentor
2, Recon
3, Sixth Sense

Driver
1, Clutch Braking
2, Smooth Ride
3, Off-Road Driving

Gunner
1, Deadeye
2, Snap Shot
3, Brothers in Arms

Loader 1
1, Intuition
2, Brothers in Arms
3, Camouflage

Loader 2
1, Safe Stowage
2, Adrenaline Rush
3, Repair

Radio Operator 1
1, Situational Awareness
2, Signal Boosting
3, Relaying

Radio Operator 2
1, Camouflage
2, Brothers in Arms
3, Repair

The 3 perk macimum is not true, i have aeen a guy working on his 5th skill for his crew. It just does not become feasible to go very hight because for every extra skill/perk you want it will be doible the exp needed.
Skill/perk 1 = normal exp
Skill/perk 2 = double exp
Skill/perk 3 = quadruple exp
Skill/perk 4 = octuple exp
Skill/perk 5 = 16x exp
(From the oginal amount)
So on and so forth.

" The Brothers in Arms Perk (...) provides no benefit whatsoever unless all of the crew have it trained to 100%."

So training BIA in any other way then on the whole crew is a waste

that is very correct. BIA is a perk very discussed. some people say its awesome some say its a waste

EDIT:
i though i shoudl add a bit to the comment. and also my personal opinion on the perk

i think this perk is good if used in the right tank. because in fact 5% extra primary skill means:
commander - see further 5%
gunner - turret rotation and aim time 5% faster
driver - extra 5% accelaration and 5% turning faster
loader - 5% faster reload (remember the difference a shell rammer does? this is half of that difference on top of the rammer )
radio operator - 5% further comunications distance. (this is probably the bonus that makes least difference.)

in short. if you think improved ventilation class is worth having you probably will think BIA is worth it. after all is exactly the same bonus!!!
