"Steel Knight")[2] is a Japan-exclusive video game created by General Support which was originally released for the NEC PC-9801, and later ported for the Super Famicom.

Before each mission, a basic summary is given in Japanese in addition to unit strengths, and the locations of major cities.

Each mission has the player either invade the enemy, withdraw from an untenable position, or defend occupied territory.

The rate of accuracy in combat is entirely dependent on the distance between the opponents along with a degree of luck (to determine whether the bullet penetrates the target for a hit or not).

The timespan of the Super Famicom version of the game is from June 1941 to September 1943, approximately the duration of Nazi Germany's forward offensive moment in the Eastern Front of World War II,[3] but the NEC PC-9801 version of the game extends the timespan to March 1945, when the player has to defend the Third Reich from the invading Anglo-American forces.
