Some interesting details here:
_ " The T-10 Parachute is a series of static line-deployed parachutes used by the United States armed forces for combat mass-assault airborne operations and training. The T-10 parachute was introduced in the early 1950s. In 1976, the B model introduced the anti-inversion net; in 1986, the C model was introduced, which changed the pocket band free length from 4" to 7½". The T-10D, adopted in 2000, includes the detachable pack tray, which in itself includes the 15’ universal static line and 5’ extension static line. The T-10D is currently being replaced by the T-11 parachute system. In 2006, all T-10C parachutes were revised by adding one static line stow bar to each side of the pack tray; the material for the T-10C was also changed to the Army’s Foliage Green #504."
_“There are derivates using this general design, like the MC1-1B parachute. The basic canopy is the same as the T-10B assembly, except that there are orifices or cut-out areas in 11 of the 30 gores, creating a gliding type descent. The canopy has two control lines, each extending from an outboard orifice to toggles which may be manipulated in such a way as to make 360° turns. It has a 3 3/4inch mesh anti-inversion net attached to the skirt of the canopy that extends 18- inches below the canopy shirt.”
