You have to remember the Challenger 3 is not a new tank but an upgraded 2, now originally they were planning to not upgrade them all, but they are now talking we may need more MBT’s for the defence of the Country and they have to come from somewhere. I would have liked to have seen double the number provided and who knows we may increase the number, but we are a small military these days and in comparison there are well over 1000 Leo’s floating about amongst countries.
This is what you get when the Cold War ended and the West reigned in their military spending and prostituted themselves to Russia for cheap energy.
The Soviet Union bankrupted itself trying to keep up with the arms race, using energy it has both financed its military and bought in technology that before the wall came down was basic at its best.
The worst thing is the west did sleep walk into it.
