Can anyone tell me what "IRBMS" are. I know about ABMS and ICBMS, and
S.R.B.M. as well as M.R.B.MS are but never read anything till here about
"IRBMS".

IRBM = Intermediate Range Ballistic Missile.

It's the class of ballistic missiles with a range somewhere between 1.500
and 3.000km. They are not "intercontinental", but also not "tactical" or
"short range".
