A U.S. Army Abrams 120mm cannon destroyed a T-72 tank more than 5,000 meters away using a next-generation guided tank round able to find its own way toward a target, service officials said.
The December test at Yuma Proving Grounds, Ariz., was staged to prove that the guidance system of the Mid Range Munition (MRM) would work when fired.
The MRM has two guidance modes.
The first is laser designation, in which the round follows a laser spot generated by some other target seeker to the target, or in so-called offset mode, near the target.
The second is with its 3-inch infrared camera. The guidance system compares the IR images to a target library stored in electronic form.
"The algorithm running through the round is looking at the environment and differentiating the target from items that might be in range in a normal desert environment," said Jeff McNaboe, Army MRM program manager.
In the December test, the round used only its infrared seeker, the first time it had destroyed a target without laser-guided help, said David Rigoglioso, deputy product manager for large caliber ammo, Picatinny Arsenal, N.J.

I think part of the idea is to divide the R and D costs between multiple projects (they've got a 155mm howitzer shell for the M-777, the XM982 Excalibur, and ATK is using pretty much the same technology for the precision guided mortar round and the Navy's extended range munition).
But I do understand why they want that kind of range for a tank shell.
The M1A2 has about 5 times the operational range of SP artillery, is better protected, with a good loader has a 20% better rate of fire than the M-777 (6 rounds per minute rather than 5), and with this round can provide more accurate fire with far less collateral damage. It also takes less than half the crew of the M-777 or M-198 Paladin (9 and 8 crewmen respectively) and only one more crewman they they wanted to use in the Crusader (3). It's a pretty cost-efficient response to the cancellation of Crusader.
The only problem, as I've said, is making that kind of range practical from a guidance standpoint. That means proliferation of laser designators, at least in my mind, given my lack of faith in the IR system.
