Not sure if anyone cares, but the markings on War Machine actually have real-life meaning.
ED FLTS 445 means the unit is assigned to the 445th Flight Test Squadron operating out of Edwards Air Force Base. The 445th is part of the 412 Test Wing, which has a long and storied history; they are the personnel who tested (and continue to test) the F-22 and F-35.
The 001 is the last three digits of the unit's serial number, so War Machine is the first operational unit off the production line.
Now, the confusing bit, for me. AF 57 means the unit is assigned to the Air Force, and was ordered way back in 1957. Maybe that year has some significance in Marvel or Iron Man lore?
I'm also interested to see if they explain why, even though War Machine is an Air Force machine, all the drones seen in the trailers are Navy (apparently assigned to the VX-23 Salty Dogs).

Oh, and I got mine today at the northside Indianapolis Wal-Mart, where they had one or two cases' worth out on the pegs.

Edit: apologies if this was already posted; I skimmed a couple of pages in there...
