In my opinion, it is far preferable to enlarge the active duty services than to lift limits on reserve and guard service, which in many cases is already being over utilized. From the AP via Military.com:

The Pentagon has abandoned its limit on the time a Citizen-Soldier can be required to serve on active duty. . .

The Pentagon also announced it is proposing to Congress that the size of the Army be increased by 65,000, to 547,000 and that the Marine Corps, the smallest of the services, grow by 27,000, to 202,000, over the next five years. No cost estimate was provided, but officials said it would be at least several billion dollars.

Until now, the Pentagon’s policy on the Guard or Reserve was that members’ cumulative time on active duty for the Iraq or Afghan wars could not exceed 24 months. That cumulative limit is now lifted; the remaining limit is on the length of any single mobilization, which may not exceed 24 consecutive months, Pace said.

In other words, a Citizen-Soldier could be mobilized for a 24-month stretch in Iraq or Afghanistan, then demobilized and allowed to return to civilian life, only to be mobilized a second time for as much as an additional 24 months. In practice, Pace said, the Pentagon intends to limit all future mobilizations to 12 months.
