Very interesting concept on the transition into a grunt

Retired Army Maj. Gen. Robert Scales, chairman of the Pentagon's Close Combat Lethality Task Force, has suggested that Marines should have to go through four years in a different career field and wait an enlistment before transitioning into the infantry.

As part of this effort, Scales — an Army field artillery officer who earned the Silver Star in Vietnam when his base was overrun — has been working to convince the Defense Department that soldiers in their mid to late 20s are more lethal. The retired general told Military Times this is, "the optimal age for a close-combat soldier."
