I asked about the title, because I thought maybe the game was intentionally obtuse as some sort of satire of neoconservative fondness for military interventionism, which leaves the soldiers having to fight unknown and underestimated numbers of local forces.
If it's not that - give the player more information.
The biggest problem I had with the game, was that I didn't know how effective the weapons were. How many AT shots does it take to bring down a mech? Does AT hurt soldiers? Does MG hurt armored units? Do any of the shots actually hit?
Enemy health bars could fix that.
I also don't like the very clear cut choice between anti-infantry and anti-armor, because it feels very reactive: infantry coming - counter directly with MG; now it's mech - counter with AT; now it's infantry again...
I find the classic single target or splash (later supplemented with AA, slow, poison, sniper, etc.) a much more interesting, even if overused, choice.
If you need any more suggestions on how to make your game more generic - I'm your guy Edit:
Just noticed that it's the Finished section, not the Feedback. I hope you don't mind the critique.
