Branch and name tapes over the pants' backpockets

Hello everybody,

Sometimes (very seldom, indeed) one can see the US Marines and soldiers wearing camouflage pants with name tapes (branch tapes) knitted over the back pockets:






Is it against the US military regulations?
What is the practice of wearing these identification tapes?

Any other comments and ideas?

Thank you in advance!

I dont know anything about it, but just came across this feature recently on this navy set:

so this should be legit?

I'd guess, such name patches are used for hot weather,when the combat jackets with standard name, branch tapes and the other ID pathes are not worn.
Name tapes on velcro are also used on the back side of the patrol caps...
