14. Stoppages.-a. General.-(1) A malfunction is an improper
action of some part of the gun, resulting in a stoppage; for example,

(2) Any accidental cessation of fire is a stoppage. It may be a
faulty cartridge or a malfunction of some part of the gun. The fact
that all the ammunition in the belt being fed into the gun has been
exhausted should not be called a malfunction, since it is a cessation
of fire from natural results.
(8) Immediate action is the term applied to that operation re-

during, and after firing will greatly reduce the liability to stop-

of the reason why stoppages generally occur. Prevention is the best
remedy for all stoppages.
Caution: After any stoppage which appears to be caused by insuf-
ficient recoil, make sure that the bore is clear before continuing firing.
It is possible that such a stoppage (for example, one caused by incom-
plete ignition of the powder charge), may result in the bullets lodging29
