So the scruffy RAF types standing around the fast food stalls are assumed to be army.
Result!!!!!!!!!!!!!!!
You don't have to go far back to the time to the period when we regularly had RAF personnel doing their shopping in town. They had so many variations in clothing that to use the word uniform was a misnomer.
The best way to determine if the camouflaged troops are airforce or army is by eye.
If the wearer looks like a sack of sh*te with an ill fitting uniform thats airforce. If the uniform fits well thats army.
