>they are still used in that role and quite widely
other than specialised units such as the US air assault division, nearly all countries don't use helicopters as "battle taxis"; that is, they don't expect helicopters to come under light harassing fire
the main reason for armouring "battle taxi" APCs is that you expect them to be shelled, so they need a certain degree of artillery fragment protection
helicopters aren't expected to even survive that much, otherwise they'd be armoured more like AH-64s than MH-60s

I mean that it wasn't an insurmountable problem that precluded their use altogether; as I said, the air force could bomb open an LZ, or more realistically, SF could be dropped to blow an LZ
