The Author of the CAT article proposes that a company of such vehicles be available for attachment to any field force that needs them. Such a company might also be strengthened by Sappers mounted on heavy IFVs that can also serve as anti-infantry tanks to support the CATs. A platoon of 120mm Assault Gun mortars would also be useful for this force. If based on a vehicle such as the Bradley these could be used in a direct-fire MOUT role when necessary. The CAT idea could easily be adapted to an Abrams platform, though it would be desirable to fit a diesel powerpack. Russian sources claim that the destructive effect of the 120mm Mortar rounds used with their Nona-series weapons is on par with 152mm/155mm Artillery Shells. The Abrams CAT may serve a dual role, since I can see the vehicle resembling an updated version of the M728 CEV.
An A-frame mounted on the turret might negate the advantages gained by the shorter mortar gun tube but this capability could be retained by fitting the booms ot the hull, as is done for the AMX-13 based VCG vehicle. Such arms may be useful in the deployment of infantry ladders and a camera pod could be mounted on them to let the crew look into higher story windows or see a longer distance in close terrain. When not being used for urabn combat such an engineering vehicle would be a useful supplement to vehicles such as the Abrams Grizzly
