Friend or Foe ID Flag - Should you become lost or separated from your unit, when approuching friendly lines or a friendly patrol it's best to carry something that will quickly identify yourself as a “friend” and not a foe. And there's nothing more recognizable than to carry & wave a small 12 x 8 inch Amerian flag. Better to wave a small American flag then a “white flag” and risk being shot at and mistaken for a foe by your own troops. Ya know?

Actually that quote makes me believe that Ranger Rick has actually served in the US Army.

But then again joining up is not really a good way to ensure you die in your sleep aged 102 in a comfy bed surrounded by your relatives. People shoot at you and try to blow you up when serving in the military and the enemy tries to do so also.
