Shoot, move, communicate, detect, avoid detection.
BIA (Brothers in Arms)
Only works when all the crew has it 100 percent
The simplest way is to just choose BIA for all crew members as first skill.
Shoot Move Communicate (Commander, Radio Operator, Gunner) skills generally first, then Survival Skills (Note Commander one of first skills is 6th Sense versus Shoot/Move/Communicate).
Commander (Cdr)
6th Sense
Situational Awareness on some vehicles
Radio Operator (RTO)
Situational Awareness
Extend or Relay Signal
Gunner (Gnr)
Deadeye
Designated Target
Loader (Ldr)
Concealment
Repairs
Fire Suppression
Driver (Dvr)
BIA
Off Road Driving (Helps to increase speed off road)
Controlled Impact
A skill Loader does not have
Reset skills. The cost to reset skills is about 20,000 silver or 100 Gold (Subject to change by WOT). Sometimes I will choose the the first skill for the Commander, Gunner, and Radio Operator as listed above, generally once the second skill gets to 40 percent you can reset
the skill and get BIA to 100 percent but you will loose most of the second skill, it will generally drop between 0 and 10 percent.
Swapping Crews Between Vehicles
Crews with skills can be swapped between vehicles and trained to 80 percent or higher, the skills will not kick in until they are 100 percent trained or you can pay 100 gold to get them to 100 percent. Generally within the first 30 battles after swapping they are up to 100 percent trained.
What you choose as skills may depend on the type vehicle your playing (Heavy, Medium, Light, TD, Arty). I choose repairs and fire fighting last, instead I use repair kits and first aid kits to compensate for not having those skills. Generally I don't pay for the repair/fire kits to use them, but I will on occasion, Arty is generally a one shot, so I don't buy them but I will use them if I have them in depot.
