When at close range, the larger shells like a 155mm would surely take out an MBT. But beyond maybe 15-20m, not likely. In real life, at that range the only real damage to an MBT from an HE round would be damaged external unarmored components and loss of externally-mounted equipment. Nothing that would need to be simulated in PR.
But with blast-based munitions such as the JDAM, even the smallest 500lb warhead is likely to jack up a tank at 30-50m. If the tank itself isn't wiped out, the crew inside would still be in a world of hurt.
As for longer ranges though, the 155mm HE is probably going to still cause casualties beyond 40-50m, due to shrapnel and projected debris. But armored vehicles and soldiers behind cover would remain relatively safe. The JDAM and similar munitions would likely not have any serious effect at extended range though, due to their minimal shrapnel projection.
That's the main difference between the two types of attacks. You have either "Blast" or "Fragment", rarely both.
