When playing as a tank commander in a tank that has a 4 man crew, a modded vehicle. The AI does not engage with main gun and rarely engages with anything else, the system in place only allows for a 3 man crew but tanks can have up to 4 man crews.
The AI needs to be corrected to include the presence of a 4th crew member so that playing as a tank commander is more fun instead of dying all the time because the AI doesn't know how to engage.
