Personnaly id look into getting one of the fatigue mods rather then suffer the stock fatigue model. You're quickly going to find yourself playing "lemmings in das boot" from juggling them around so much.
Acutally, if your not into fine tunning/modding your game, id grab the latest version of the Grey wolves mod. ( link here:
