What for? Has it been tried (other than during it's initial trials) in desert warfare? I can't see them coming up against any main battle tanks out there.
Joseph, tanks can be quite effective in a Counter Insurgency Environment, the Canadian Army used tanks in Afghanistan quite successfully. We would put them in Observation Posts and use the main gun to provide over watch with very precise fire at very long distances (up to 5000m). You can destroy a grape hut with a tank round and not worry about collateral damage without the enemy being even aware of what happened or what hit them.
The Taliban referred to our Leopards as fire breathing dragons. We also used them rather unconventionally in roles such as Convoy Escort and Reconnaissance. Modern tanks are actually great surveillance platforms because of their advanced optics and laser ranger finders. Our Leopard 2A6s have a Laser Range Finder that is effective out to 10000m.
We would also use first the Leopard C2 and later the Leopard 2A6s to escort convoys as they were basically impregnable to any IED the enemy built and trying to ambush a convoy escorted by Leopard 2A6s is a very big mistake. When we first sent Leopards to theatre, the Taliban didn't know what they were or their capabilities and engaged them with RPGs and Small Arms. That particular engagement ended very poorly for them with the tanks simply turning on their position and running them down while peppering them with 120mm HE and Coax fire.
The Brits, Americans, Dutch, French, etc were all skeptical of our and the Danes use of tanks in Afghanistan until they saw what the machines were capable of. After that, they were in high demand. The Brits would make regular requests to have our Tanks attached to them for clearance operations. Just another tool in the toolbox and one that the Infantry closing with and destroying the enemy are thankful to have when they are available.
As for a couple of tips for operating in the Desert, umbrellas and cooling suits for the crew are a must. The machines will perform well but the crew need cooling suits to be able to operate effectively.
