Clone armor was designed by Jango Fett and so slightly resembles Mandalorian shock trooper armor. The different colors represent different ranks, with yellow meaning commander, red meaning captain, blue meaning lieutenant, and green meaning sergeant.
Stormtrooper armor was designed to withstand harsh conditions and indirect blaster fire. It could not withstand head on fire. Rank was indicated by a color pauldron.
Mandalorian armor was the most recognizable part of Mandalorian culture. The "T" shaped visor can be seen in the clone and stormtrooper armors. Mandalorien armor sometimes had armor mounted weapons such as flamethrowers and wrist-mounted rockets.
