Yeah, try to make your training missions cool. For instance, have a CQB training course where, within a certain time, you have to move in and neutralize the targets inside a mockup of a Somali building. You could have red targets for hostiles and blue for friendlies, and if you shoot a friendly, you fail. This would be really different, but you could only do it alone because OFP soldiers can't fight CQB for sh*t.
