Women and some men having trouble meeting new Marine Corps standards

AP/Marine Corps Times:

New physical standards established so women can compete for combat posts in the Marine Corps have weeded out many of the female hopefuls. But they're also disqualifying some men, according to data obtained by The Associated Press.

In the last five months, six out of seven female recruits — and 40 out of about 1,500 male recruits — failed to pass the new regimen of pullups, ammunition-can lifts, a 3-mile run and combat maneuvers required to move on in training for combat jobs, according to the data.

The tests, taken about 45 days into basic training, force recruits who fail into other, less physically demanding Marine jobs. And that, the Marine commandant says, is making the Corps stronger.

The high failure rate for women, however, raises questions about how well integration can work, including in Marine infantry units where troops routinely slog for miles carrying packs weighed down with artillery shells and ammunition, and at any moment must be able to scale walls, dig in and fight in close combat.

I think they must mean mortar shells, and not artillery shells, which are usually not carried by the troops on a march.   The failure rate for men is actually lower than I expected, but those who cannot keep up may have been culled in recruit training.

The Marine Corps screening process is intended to reduce failure in combat.  Those who straggle and fall behind, become a burden to the rest of the troops and danger to themselves.
