And while a hit's far from guaranteed, a fin round's a lot faster than an ATGM, and if having a pop at the helicopter means it evades... for most CLOS systems that's going to put a big wiggle in the missile's flightpath.
I remember a Lynx pilot talking in 2003 about his experiences of having a crack at some T-55s with TOW - from a bare-arse* firing position.
At least one missed due missile/operator error, and another missed when he dropped the collective to avoid ‘return mail’ in 100mm format...
