Chieftan was originally called just Assault, but for a reason only known by the authors and folks involved the name changed to Chieftan. The game was published as type-in in the Giant Book of Spectrum Arcade Games.
It's mainly a shoot 'em up with just one tank cruising one of four platforms (or roads) above you. You control the artillery cannon in the bottom of the screen and shoot a load at a time.
If you miss 3 shots you lose the game.
There is no scoring, no levels so it's a bit pointless.
