Attack Heli Class Glitch/Cheat?

[AloneAgainXO]

I've been getting killed by attack helis that show fire extinguisher equiped, but the ECM smoke is activated. Same with heatseakers equiped, but TOW missile is being fired (not the TVMissile, I've seen two missiles launched and destroy armor).
Is this a class glitch or some sort of cheat that is not known?

Will try to get screenshots/footage.
