Well not my fault they had awesome power armour that probably can kill a squad of marines in not so awesome power armour.
Power Armour, Exo-Skelteton, Robot Armor, Powered Suit, Armoured Powered Suit, Mjonir Armour, etc.
Power Armour basically enhances speed, endurance, strength of the wielder. The planes in robotech can be seen as power armor. While the destroids was more robot armour. The armour in aliens was an exosuit.
Man I need to read troopers again. I found some anime that was closer to the book than the movie was.
