BasicLoad,
"Magazine supported low-prone."
I cannot say I've ever heard that taught anywhere by anyone.

3-2. MALFUNCTIONS
Malfunctions are caused by procedural or mechanical failures of the rifle, magazine, or ammunition. Pre-firing checks and serviceability inspections identify potential problems before they become malfunctions. This paragraph describes the primary categories of malfunctions.
a. Failure to Feed, Chamber, or Lock. A malfunction can occur when loading the rifle or during the cycle of operation. Once the magazine has been loaded into the rifle, the forward movement of the bolt carrier group could lack enough force (generated by the expansion of the action spring) to feed, chamber, or lock the bolt (Figure 3-1).
(1) Probable Causes. The cause could be the result of one or more of the following:
Excess accumulation of dirt or fouling in and around the bolt and bolt carrier.
Defective magazine (dented, bulged, or a weak magazine spring).
Improperly loaded magazine.
Defective round (projectile forced back into the cartridge case, which could result in a stubbed round or the base of the previous cartridge could be separated, leaving the remainder in the chamber).
Damaged or broken action spring.
Exterior accumulation of dirt in the lower receiver extension.
Fouled gas tube resulting in short recoil.
A magazine resting on the ground or pushed forward could cause an improper lock.
