Occam's said it correctly.
Anyone that thinks this is acceptable is wrong. What kind of intel did those hog guys get on the ground? Shouldn't an O-4 and an O-5 KNOW that orange panels meant friendlies? Yes, they should have.
I still believe that this is a problem of taking reserve guys that have only seen the local range for the past 20 years and dropping them into a combat situation. How many guard units go to red flag? Especially hogs. Are they even invited? Many of these guys are part-time and fly airlines for a living. It's a hobby for some. Now, suddenly, they're thrown into combat and it seems that some of them don't want to RTB with any ordinance.
If they would have taken their time, talked about it to each other a little more in-depth, coordinated with the ground FAC and ABCCC, they MIGHT not have strafed the Brits. Instead, they were in a hurry because they were low on gas and the Lt.Col was determined he was going to attack that column.
Believe what you believe. If you pull the trigger or push the button and kill friendlies, YOU'VE F-D UP.
Thanks for the orange post. It sticks out like dog balls, yeah?
