well, as always, i disagree..
the thing is: tanks need to be restricted quite a lot.
1 tank / 1000 is not so much.
if you just take 2*minimum LI and then buy a "good" tank -> broken army..
also, a tank is not necessarily a grizzly.. there are a lot of tanks which are not the god of the field.
think more in the line of T-62.
3-4 rocket hits from the small multi shot WZ rocket launchers (RL-RPG is one shot and run, i gues..) should kill it - just like any bigger vehicle (skimmer, hur, EDD,..)
the main gun is not very useful against infantry, what remains is the ubiquitous MHMG...
if you think of WWII, the infantry stood a good chance against tanks in a rough environment, like rubble, cities or more dense environment (stones, trees, a facility..).
the grizzly, of course, could only be broken....
donīt throw the tanks away, they are against inf. just like the hurricane (mhng) + a good AV gun
