We talkin Troopers just on the ground or do they get vehicles and equipment? They have Droid Poppers, which're basically grenades that fry droids and other machines. And considering a stick of homemade dynamite was enough to blow a T-800 in half by being wedged in its side would show that Blasters and the other weapons at the Troopers disposal are more than enough to get the job done. T-850's are tougher. The T-1000's are shapeshifting liquid metal, and their greatest vulnerability is extreme heat. Which is pretty much every blaster and lightsaber out there. With a bunch of Jedi out there, the HK's and other things get taken out hard. And if the Clones have walkers and heavy artillery they could do a lot of damage on their own, though many of them will still die.
You have to remember though, it was a lake of hot steel that still took along time for the T-1000 to die in. A Light Stabber killing it is highley doubtful since it took the T-1000 awhile to melt in a huge lake of heat.
