crotales are relics now. I remember seeing them in the 23rd March Pakistan Parades since Gen Zia
my father was originally a gunner but then moved to AKK AKK (renamed as Air defence or in late 90s) and served at Kahuta and in NWPF (along Pak Afghan border during 80s) and of course in Saudi Border town Sharura during KSA's limited war with Communist Yemen.
During my on field visits to deployment under his command as battery commander thats what I can remember it would have PAF operated radar, a about 4 or 5 twin barrel 37MM Chinese AAAs and two or three 4 barrel Shilka (towed version). And one or two 12.7mm. since I am talking about 20 years ago so I cant recall the exact number. I dont recall seeing any missile systems my self including RBS70 or other shoulder mounted missiles. If permitted I would run toward a 37mm, sit in its chair and turn its wheel while the gunner would explain how the cross hairs work. (no I never fired it)
