lvt is the best town buster. 75 mm with a fast rate of fire
Naaw... the Ostwind. Highest rate of fire for the 37mm in a GV, and loads of ammo. 2 Osties can knock down a town by themselves in under 5 minutes. If you use the hull MG on the gun batteries, just one can take 100% of a town down.
Town Building requires 250lbs of explosives to take down. Ostwind 37mm = 15.6 lbs of explosives. So, it takes 16 shots with the ostwind to take down a building... not taking into account that some buildings will be damaged next to the one you are shooting.
Town has 53 buildings in it. Ostwind has 1000 rounds of 37mm. So... 1000 rounds / 16 rounds per building = 62.5 buildings worth of "boom boom". This gives you plenty of ammo to wreck a town, and take out the auto guns, and still have your hull MG as a backup. And... with the rate of fire on the 37mm at 480 rpm... this makes the time to take down a town in a SINGLE ostwind (assuming you dont have to move and re-aim, and you expend ALL your ammo)... just over 2 minutes. Taking into account that you have to move, re-aim, some shots will miss, etc... Lets say 5 minutes. And that is with ONE Ostwind. Never seen it done in that time, as you usually end up having to dodge opponents... but it "could" be done.
Never... never... let an opponents ostwind into your town.
