Striker

"Striker is a set of rules for science fiction ground combat using 15mm miniature figures. Each player will command a force ranging from a platoon to several companies, consisting of from a few dozen to over a hundred men, plus artillery, armored vehicles, and aircraft. The rules are intended to be easy for the beginning player to understand while at the same time providing a comprehensive and detailed treatment of ground combat from the beginning of the 20th century to the far future."

"The science fiction background of Striker is drawn from the universe of [the role playing game] Traveller. All weapons and military technology described in Traveller are included in Striker. These rules may be used in conjunction with Traveller or by themselves; no familiarity with Traveller is required."

Striker was reprinted in 2001 in the Traveller compilation book "The Classic Games", released by Far Future Enterprises.
