CLASSIFICATION Light Tank NAME Mercury X-10 Recon Tank The Mercury X-10 is last generation's MBT. However, now 20 years old, it is today obsolete in this role. The Serafino Tool Works took several of these obsolete tanks and modified them to perform as Recon Tanks. With the offered X-10 upgrade costing one tenth the price of a new tank, many nations jumped at the chance to utilize their otherwise obsolete equipment. The Mercury has the battle tested 105 mm Caesar Anti-Tank gun, Commander's 40 mm Mini-gun and laser sighting system, and the new 990 hp Terrier engine. This tank can attain speeds of over 65 mph. However, nothing could be done to upgrade the aging Phoenix plating, and the weapon system is highly vulnerable to the advanced weapon systems of most heavier MBTs.
