capability (what the heck is "S/VTOL"?) to allow them to both
provide air

An olden days description of a plane that could do
Short take-offs or landings
or
Vertical take-offs or landings.

The usual abbreviation for this was the other way around--V/STOL.

Yep, usual was V/STOL or VSTOL as you say.
There was some use of S/VTOL (or SVTOL,
it *was* a long time ago) though. I have a feeling
they represented some difference but I'm at a
loss to say what it would have been unless it
was a preferred mode bias.
