Why No Tanks in RWBY?

Bit of a dumb question, but one I've been thinking about nonetheless:

Why are there no tanks in RWBY? I mean, you'd think Atlas or one of the kingdoms would come up with something like a tank or an IFV.

IFVs like the M2 Bradley or CV90 would be extremely effective against the grimm, the 25mm bushmaster (on the bradley) or the 40mm (on the CV90) probably being able to deal with most ground-based Grimm. For anything that has more 'armor' they also have TOW missiles capability which would also be extremely effective.

Tanks are also roughly the same, with HESH rounds and HEAT-FS rounds fired by the Challenger II and Abrams respectively would also be extremely effective against all sorts of Grimm, even the bigger types.

Standard HEAT or even small caliber APFSDS shells like the ones fired by Israeli and Chilean shermans would do the trick too.

For Aerial ones, vehicles like the Gepard and the LAV-AD exist for the purpose of anti-air.

This may be me reading too much into it but it is something I think about nonetheless as a tank nerd...
