The National Guard and Reservists protect us abroad (they make up over 40% of our forces in Iraq).
Republicans protect us from having to take care of them when they or their families get sick (ie offering them relatively cheap health insurance). Nevermind that over 20% lack any insurance and more and more are losing it every day as they lose their jobs because they're in Iraq.
They're afraid of people "gaming" the system. Oh, sure. There are so many people out there looking for cheap health care that they'll risk death in Iraq. And, anyway, it's not like we're short on recruits or anything, no need to give incentives or anything *rolls eyes*.
