Way back when I was at Willytown the aircrew were issued the green outer/orange inner jackets, and when they became worn or stained, they could return/exchange them at L Group (clothing store) for a new one. Not sure how many exchanges per year they were allowed, but I never saw a pilot in a worn/torn/dirty jacket.
The old jackets were all put in a big container behing the counter, and when it was full, the sentencing officer would check them and sign off as unserviceable. They would then be taken to the base tip and dumped.
A few of us were at the tip one day disposing of equipment packages that were too big for the bins in the hangar. We happened to notice the clothing store guys tip the jackets out into the same hole we were dumping the cartons.
We surreptitiously glanced at each other, gave a small nod and a "go slow" eventuated to allow the clothing store guys to leave.
As soon as that was done, we grabbed armfuls of jackets and jumped back into our truck and off to the section.
Trips to the dump often scored a few more jackets.
We had a few pilot mates and they were happy to take our jackets in for exchange for a new one.
This went on for over a year until an audit found that the clothing store was issuing more jackets than the base had aircrew!
Some clever officer who was on the BoS (Board of Survey) came up with the mandate that all exchanged jackets were to be sprayed with a large red cross using an indelible paint.
Bastard.
That ended the great flying jacket benefit for us troopies.
I still had three nice ones when I got out many years later.
