JMA:

At what distance from the (potential) contact were the LZs, typically? And how often did the LZs end up being hot?

I ask because, as I remember ZANLA and ZIPRA, they had a relatively low ratio of RPG-2 and RPG-7s, and weren't terribly competent with mortars, heavier MGs, or RCL. I'm wondering how much adjustment might be necessary against a Taliban opponent who has a long history (dating back to the Soviet era) of using those weapons against helicopters LZs.
