Yes, it is just replaced by the Grille 15, just like what registered user said.
Grille has one of the best guns (accuracy wise) and can keep up with most "hovercraft" mediums
fyi : WG has a track record of replacing the old tanks with new ones for balancing reasons and players just get all their XPs, crews and so on transferred
Examples:
i.) replacement of t30 by t110e5 as the tier 10 heavy tank
ii.) replacement of fv4202 by the Centurion Action X tier 10 medium
for the t30, players who own it gets the t110e5 for free and a complimentary t30 tier 9 TD as well. As for the Action X, players who own the fv4202 gets the new tank for free while the fv4202 gets dropped down to being a tier 8 premium. Dont really remember whether they get the FV for free or they have to grind it in a marathon mission.
