rush at one of the little thingies that spawn enemies, and just fight it. got me a lot of ether which i used to upgrade myself to stand a better chance to fight it which got me ether.. etc etc
hand to hand isnt necessary, and im not just saying this in fear of my troops dying :) i just want my soldiers to fire at troops 5 feet in front of them, and bazookas not to fire at enemies 5 feet in front of them.
agree with the sell option, even if its less or even 0 points back i wanna get rid of excess troops made me lose some good ones.. also i would like to point out that when you pause arty/plane still bombs you.
