That's exactly what it means. You take hold of the strap to lift what's inside out of where it was. Dead, injured, wounded removed from vehicle/boat/etc. Especially when whatever is inside the clothing can't assist, or more gory.

Issued to armored crew members. Used for pulling injured/unconscious crew out of tanks/armored vehicles.

Almost the same as a flight jacket except for the strap. In fact, we as flight crew were issued the “tanker” jacket when stocks of the flight jacket wasn’t available.

We’re talking US Army aviators, not Air Force.

For a while, the original 2 piece flight suit was also issued as tankers uniforms. 1980s

No they aren't, those are for extracting wounded from situations when they can't help. You use them to drag a man across the open or haul him vertical right out of an armored hatch. You sound like a surplus store owner that perhaps hears too much rumor from his clients.
