some server disabling vehicle TK/TW, so all of the method not working, the way i see is, just spamming the smoke on the tank or if you got another tank, try to block his view

or, when the engineer trying to repair the tank, kill them

like i said earlier, that's for server enabling TW/TK on vehicle, i've seen server with TW/TK disabled on vehicle, thus no damage or whatsoever to friendlies (C4-ing, grenading, RPG, AT4-ing, CG-ing).

i haven't try that yet, though i tried inflicting damage to the tank and seeing still intact, i decided suicide, respawn with smoke grenade and keep smoking them.

perhaps in admin side, direct message him to GTFO or move to other team or kill him? -- reason, tank camping

it's gonna be hilarious must say
