Starship Troopers: Prepare For Battle! should not be confused with the original Starship Troopers wargame, also by Avalon Hill, published in 1976.
Starship Troopers was based on the Heinlein book. Starship Troopers: Prepare For Battle! is based on the film version.
This is a fast-paced tactical wargame which begins simply and then adds additional rules with each new scenario.
Note that the original Starship Troopers game has completely different rules, maps, units, etc.
