I'll go a step better, this entire unbalanced side problem could easily be fixed with probably 2 lines of code.
If a side has 25% more people than the other side, disable C-47/Jeeps.
10 vs 7 - game goes on.
10 vs 6 - capturing is temporarily halted until sides are re-balanced.
Not perfect, doesn't take into account spies, idlers, etc, but it's better than just letting people wail on the pinata.
