There are several branches of the military, as you can learn from these emoticons. (They are free for veterans and free... for everyone else, too!) There is the NAVY (which blows up other navies); the ARMY (which shoots other soldiers on the ground!). And there is the AIR FORCE (which flies airplanes!).
The COAST GUARD helps people survive natural disasters! And POWs... are PRISONERS OF WAR. Anyway... we have a flag for all of these organizations. You can download them... if you support their cause. Click here to download. Because they are amaaazing. They belong... on MSN Messenger!
