Robert Heinlein equiped the Mobile Infantry with powered armor exoskeletons in 1959's
Starship Troopers. Johnnie Rico had it long before Ripley and it was nuclear powered.
Starship Troopers is still on the reading lists of the United States Army, the United States Marine Corps and the United States Navy. It is the only science fiction novel on the reading list at four of the five United States military academies.
"No, they've got no time for glory in the Infantry,
No, they've got no use for praises loudly sung,
But in every soldier's heart in all the Infantry
Shines the name, shines the name of Rodger Young!"
