Cable possesses superhuman physical endurance,
Cable is literally fast enough to evade high-powered bullets in-flight (after they have been fired), and even has the ability to visually track rounds after they’ve been fired (though they are not easy to see, except through his cybernetic eye).

His techno-organic bodyparts possessed minor superhuman strength and durability.
This is actually not inconsistent with Cap's capabilities since many people consider Cap to have low level superhuman strength.
