However, the Fatboy is particularly vulnerable to Aircraft, Submarines, and any other Experimentals that can get close enough to fire their main weapons. Its long range (it is only outranged by some sea units, and all the different artillery pieces including the Scathis and Mavor) and incredible DPS makes it very effective when kiting other Experimentals and smashing defenses. The Fatboy is best used as defense against other ground Experimental units, or as a forward firebase. Its weaknesses are offset by its long range and high damage output. However, it is very slow moving and susceptible to heavy air units and requires support to increase its Survivability when the enemy has air dominance.

When on land and not moving, it can also produce any land vehicle the UEF posesses, enabling the Fatboy to create a land army or an air support squad within minutes. The Fatboy is considered by some to be the most versatile unit in Supreme Commander, being amphibious, shielded, and equipped with a wide array of weapons including Hells Fury Riot Guns, Linked Railguns, Angler Torpedos, as well as four high powered triple Gauss Cannons. This is an experimental unit, as well as a factory, direct fire unit, anti-air unit, defense unit and an air support unit. The UEF Experimental Mobile Factory, nicknamed the Fatboy, is a UEF unit.
