Is the Airborne still in vogue? What about the US?

Who told you the developed world "did away with the airborne"? And what is the 101st Airborne Division in the US?

You said by helicopter "directly to" and then drag the rope to slide down the kind of airborne troops, our country also has, is the Army Air Corps.

Additionally, parachute landing and airborne landing are two different things: parachute landing is actually airborne, meaning high altitude landing; airborne landing is from a low hovering helicopter down. Airborne troops in our country is the air force, airborne troops in our country is the army.
