Wikipedia, my favorite source on anything, has an article on man-to-man wargaming, aka skirmish wargaming. The history of this style and also the difficulties in game design are interesting.
Reading this motivated me to google best skirmish games and i found some but after examining the descriptions I had to wonder why anyone would pay $50 for something when existing rule sets can be applied to any scenario if you are creative about modifications. It does not matter whether your soldiers are mechs, orcs, or knights in armor; just adjust the points and play! That is more fun than buying canned rules anyway.
