Of course this includes AT guns, which probably accounted for the lion's share of losses (the article, like Redleg, talks about indirect artillery causing the odd "lucky hit").

I agree with Seamus, WW2 AT guns could be deadly, especially with the element of surprise. The German 88mm gun is the clearest example. But their weakness is that once their position is revealed, they are very vulnerable to artillery or other means of attack. The Finns excelled at hit and run attacks, so did well with very limited AT resources. The article kagemusha links to has a nice vignette showing some Finns hastily abandoning their obsolete gun after it fired one shot. But just imagine what they could have done with hundreds of T-34s and KV-1s.
