Mantech: Robot Warriors was an extremely short-lived goofy looking weird toyline from Remco whose whole gimmick was interchangeability, like Centurions. Remco managed 6 Mantech figures and a few vehicles and a playset before cancelling the line. There was no Mantech cartoon but the was lore and it's definitely some kind of something. We get asked about Mantech a lot, even though the people asking don't know what Mantech is.
