tanks have no stealth option.
the most can do to make it hard to detect is.
perk 1 - thermal camo.
perk 2 - ir smoke.
perk 3 - nothing cos its all just cannons.

next time u see one, printscreen for me or take down the nick.

not possible for any vehicle.
dont think its a glitch, cos its extremely stupid to do in the first place...only a dumbass would do it cos its repetitive and pointless.
so most likely im guessing its a server display bug.
if i wanted to glitch, i would equip with rocket pods, guided missiles and ecm jammer or something like that

u can always check your battlelog stats under vehicles and see what unlocks are available.
