So, the U.S. knocks off a Brit, then covers it up:
Precautions have since been taken - orange panels were fitted to allied vehicles to alert pilots during the 2003 invasion. The pilots on the tape can be heard concluding the panels were "orange rocket launchers" before opening fire.
If I was a member of the resistance, that is exactly the tack I would take. I'd paint my rocket launchers orange so the invasion forces could see me clearly. Yep.
And that, my friends, is how U.S. forces offed a 'friendly'. Makes you wonder what the U.S. does to the unfriendly. Oh wait, we already know.
