I've been periodically looking at the issue of track reliability and I'd like some input from the ex-tankers here. A friend of mine indicated that throwing a track is actually really hard, and that artillery would have to land pretty well within a few feet of a track to have any chance of scoring an immobilization on the tank. Likewise, direct fire on track links and rods made of modern steel isn't going to do a heck of a lot either, afaik. Yet there seems to be this consensus on the internet anyhow, that tanks can be immobilized if they are so much as sneezed at by RPGs, low calibre HE, etc. What is the truth?
