no, not for the I44 tanks, only with non I44 tanks i will get crew.
the Request crew in the action menu dont show up at all no matter what tank for I44 mod, it only shows up in vanilla arma tanks, and any other 3rd party addons that are ww2.
there is a panzer 2 tank in I44, which is a 3rd party addon that they got permission to add to their mod, and the crew request works on that tank, when i request the crew i get 2 AI, as its a 3 man tank.
