Definitely a possibility, but it's still a question of cost benefit analysis. PA is going to be fuckall expensive.
The suit in crisis is described as being worth a billion dollars. Even assuming we could develop that tech in the next 10 years (doubt.jpg), could you reliably assume that one man in such a suit would destroy 1 billion+the cost of training him worth of enemy materiel before getting killed? Seeing as one good air strike will still BTFO this soldier, suit or no suit, it's still far too expensive ot be effectively fielded in general use.
