Heavy Combat Armor

The UltraTech class 5 Combat Armor provides 40% defense against combat damage. It requires Strength stat level 6 to equip.

The Heavy Combat Armor is close to the best you can get without continuous power. A weave of titanium/kevlar shielding panels overlays a regenerative polymer gel, and provides serious protection from both physical and energy attacks.

While not quite as effective as Powered Armor, Heavy Armor has the benefit of not requiring power (which always seems to run out in the middle of a firefight).
