Actually, they do have IFF, but they call it a transponder. Mode 3A & 3C are sub-components of military IFF (which has a number of additional modes which provide more info)
Mode 4=IFF
Mode 5c= alt
We also had provisions for modes 1 and 2 but I don't remember the details. Hit a mode 4 equiped aircraft with the right interogation code and it would respond back with a proper code and bloomers on the radar display.
