As the story goes the Swiss once tuned one to do 140km/h, made a break test, and had to send the crew to hospital. Without messing with the transmission to get higher ratios, well-maintained, optimally tensioned tracks etc. the maximum is about 90, more typically 80, the official maximum is 70. Soldiers are generally told to keep it under 60. Don't underestimate the centrifugal force of the tracks they're getting hard to control at high speeds.

Too close for comfort. I don't know what the braking distance is but I doubt 60-70 tons of steel at up to 70 km/h are that easily stopped. If that truck had to suddenly do an emergency brake, then the tank would probably just roll over & flatten it, with everyone in and on it.

I don’t know what the braking distance is

At 70km/h, 20.6 metres. For ordinary cars it's ~50m.

In a nutshell, a tracked vehicle has quite a bit more contact area with the ground, it's also kind of hard to lift the rear wheels up so you can apply a lot of break force before you start to skid etc. And Leos have the hardware to actually do that, there's a retarder in the drive train and additional disc brakes.

Have side views on dirt and on tarmac.

Wow, that's almost a full G of acceleration in a heavily armoured vehicle. Tracks are crazy. I wonder how hot the brake pads get in the process.
