Current game effects of thermobaric ammo

[Imp]

It feels overpowered to me (and my opponent) the way a single shot from a weapon would feel if it would take out (as in 100% destroy) 4 Merkava 4s in one hit.

As I said think you were lucky it will flaten IFVs 95% of the time but vs tanks nowhere near that effective, unharmed or light damage with heavy suppresion is common vs a MBT in my experience. Vs troops if anything might be more effective due to blanket effect, even if found cover somehow from the heat I would think there is no oxygen left to breath which is probably terminal.
Kartoffel worth a look at them in action on you tube, the old Tungunaska is a good view to. Also try typing in power sliding/drifting tanks or some such. Some great vids of guys messing on snow ice in MBT IFVs 60 Tons going sideways at 30 miles an hour is a bit mad, wonder what the battle computer would make of it.
