How would the military policy shift affect defense contractors?

Quoted from WSJ: WASHINGTON—President Barack Obama on Thursday proposed a historic shift in the U.S. military's size and ambitions, scaling back its ability to wage the type of war and occupation that just concluded in Iraq as the administration seeks to cut defense spending over the next decade.

Under the proposal, the Army would face a 14% reduction in troops—leaving it with too few to conduct two grueling ground wars at once, long a strategic imperative of the Defense Department.

Who in the defence business will be affected? BA seems have soared oversea order so that they may be ok. But how about the others?
