The best times for me were setting up 5 man ambushes. One to cover our rear, and then 4 in a pincer movement, on a road that bends (theres an S bend near Vybor which is great for this). I remember we hit 3 ural/v3s' at the same time, and I had an M60, which is pretty much a laser gun when prone. Ended up mullering their whole 12 man team and getting a ton of weapons in the process.
