Is it 1 repair kit used per use or per game?

churchill50: You get charged only once per game, no matter how many times you use your repair kit (unless you don't use it at all, in which case you aren't charged).The only exception is if you take two repair kits (one large and one small) and use both. In that case, you will be charged for both. If you want to verify this, just pay attention to the third tab of the post-battle results screen. It will show you how many credits were charged for consumables.
