got the teams to around level 7/8. scored 23388ish.
Fun concept! Took a little bit to get going at first, to get the teams to an almost standstill, where i didn't need to intervene much at all, but then realised the teams, and my weapons, wouldn't level up. The only push to kill the enemy, became wanting to see what other weapons and such I could get. If it was just to keep it going longer, i'd have shot a lot less.
Tricky set up to balance, getting the player to engage in battle to the right amount.
I did like how the troops weapons levels up also with tanks etc.
great job! interesting unique game!
