A body armor system that includes a fabric carrier configured (i) to be worn by a user and (ii) to hold armor plates. A back armor plate is held by the carrier. A right side plate is held by the carrier and a left side plate is held by the carrier. Straps are configured to wrap horizontally across the user and matingly connect to each other. Straps integral to the carrier are configured to wrap down over the front of the user and matingly connect to the connected horizontal straps. A right thigh plate and a left thigh plate are matingly connected with straps around right and left thighs of the user.

Body armor

A scheme for essentially instantaneous kills of fires in crew compartments s shown which is effective over a wide variety of climatic temperatures. An extinguishant is mixed according to the formula, (M.sup.+ A.sup.-).sub.sat +H.sub.2 O+fps+d @T, where A.sup.- is either an acetate in the form H.sub.2 CCOO.sup.-, chloride, or bromide, M.sup.+ is an alkali metal or ammonium, fps is a freezing point suppressant, d is a surfactant, and (M.sup.+ A.sup.-).sub.sat is a saturation level of compound M.sup.+ A.sup.- at temperature T. In one embodiment of our scheme, potassium acetate is both the (M.sup.+ A.sup.-).sub.sat and the fps in the foregoing formula. The scheme includes charging an extinguisher bottle with the extinguishant under pressure, opening a gate device connecting the bottle to a feeder line, and allowing the extinguishant to flow in the line to a nozzle. The extinguishant is then sprayed through the nozzle, which is disposed at the fire in the compartment. The scheme also includes passing the extinguishant past a container having an opening at the line. The opening has a screen barrier between water in the container and the line. When extinguishant flows past the opening, water from the container enters the line, thus offsetting water vaporization in the line and preventing precipitate depositing in the line.
