The future for defending this country is not in outdated tanks. The future is in un-maned drones. Cheap as chips compared to an Abrams. Could have heaps of them spread around the country and all controlled from the Southern citys.
Best bang for buck and if we had the numbers of them, they could easily destroy an invading forces armoury.
Would easily be able to scuttle invading ships or boats, h`mmm, the mind boggles at the uses against unwanted boats coming to our shores,
