I’d imagine they have more than choppers, which have the glide capacity of a sack of cement.
And the F4 had?
Fixed wing glide range is great, but at the end, you still hit the ground flying above stall speed (hopefully).
With a helo you can usually zero forward airspeed AND rate of descent.
Caveat - with a heavy helo, like the CH-53, your final rate of descent is still high enough that you’ll shove the landing gear up through the sponsons, unless you can do a roll-on landing to a hard surface.
