You assemble a team of infantry men and assault a variety of targets. It's turn-based combat with an interesting selection of levels.
It has a rather strange control scheme... you move your soldier with the arrow keys, but I'm unsure when one's "turn" really ends. You can press Insert to see the path you've taken this turn, and Escape lets you select another soldier. The various function keys also allow you to set different commands, and in the case of F10, restart the level.
Also, here we learn that the developer ABA stands for All Business Assist!
