They are annoying, particularly backed up with snipers.
But you can keep delaying them by using fuast then retreat, try to hide around corners and ambush it, if youve managed to get an MG to vet1, the AP rounds (use it in a building) will rip through a T70, meaning you can hold on to a fuel.
Also your calc is without any con upgrades, so that should help you fight back until you can pull that p4 out.
