You don't need an AT rifle to penetrate any kind of armor a person could wear.
Modern full body armor is 20lb, and it leaves about 60% of the body unprotected. Any kind of full protection would weigh 50lb, plus equipment and uniform being around 30lb, and pack being 50lb. Meaning a powered suit is still going to offer protection against 7.62AP at best. At which point enemy just goes up a caliber, any kind of normal sniper or general purpose machine gun would have a decent chance of going through.
And that's not even taking about frag grenades, rifle grenades or underbarrel HEAT shells that are available readily everywhere, or shit like flechettes which go clean through armor and don't weigh any more than regular rounds.
Using this powered suit to carry armor is retarded.
