WWII Glider and Medic Combat Badges Help

[Edelweisse]

Hi Folks: I recently picked up these three (3) badges...and they are all pin-back and marked "STERLING". I want to verify that they're WWII period badges/wings.

 

Two (2) Glider Combat Badges w/"raised" "STERLING"

 

One (1) Medic Combat Badge w/"punched" "STERLING"

 

I like them but I'd appreciate comments from the SMEs. Thank you and MERRY CHRISTMAS!!!!!!!!!!!!!!
