H.G. Wells, the War of the Worlds author also wrote a set of wargame rules for toy soldiers. It is interesting to read. It involves shooting toy cannons at the soldiers to make your kills.
The next set I got was Tractics. It included modern armor up to about 1980 for Cold War gone hot games. It was similar in many ways to Angriff. It was designed for one solder and one tank model were equal to one real soldier and one real tank. I like that.
