Yup, infantry can be dangerous. Wanted to take a key point consisting of 5 huts. Everything seemed fine until I got there. A Milan opened fire on me from 130 m, hidden in the grass, detracking my tank. 10 seconds later, a swarm of infantry came up behind my now immobilised tank, and started throwing grenades! And I couldnt depress my MG to get them. I felt like a turtle on his back, unable to do anything! Luckily I got away with no damages!
The other day a RPG destroyed one of my T-62s from 370m - at night and during rain!
