Between an already shrunken military, the requirements of combat in Iraq and Afghanistan, the public's perception that the war in Iraq is not going well and a healthy domestic economy, the question of how to fill the uniformed ranks is unlikely to go away soon.

The Bush administration's modest proposals to increase the size of the Army and Marines will spur the search for ideas about how best to build and keep an appropriate-sized force.
