The MC1-1B had toggles not unlike a freefall chute, but with nothing approaching its level of controls. A large opening in the rear of the chute gives the user a bit of lateral motion via small toggles. So while the T-10 required you to have decent upper body strength, the -1B could turn relatively easily. The -1C was a low-porosity version intended for higher altitude DZs, though the opening shock was much worse. Military squares are a lot like training squares, 9-cell usually, because it's all about stability when you're hauling gear. They're not as high performance as a lot of the sport chutes.
