Gepard has a range of 6km vs buk range of 50km or s-300 range of 120km. You would need a lot of them and they also don't have enough range to cover offensives.
Sounds like a good way to equip the enemy. Have you considered that you might be outside your lane here?
What was your MOS?
Also, you’re talking about conventional forces tactics which don’t really apply to this submission much.
Sorry, not US, so no MOS. My impression was that the US took a somewhat different route to air defense than the Europeans back then (and not just in terms of continental air defense).
I don't think we need to accuse each other of "ignorance" anymore, but rather we have had different experiences and a different read on the linked text.
