Sabre Force was a British Army strike force that participated in the Battle of London. Sabre Force were the unit of the Anglo-American coalition army to fully penetrate the Chimeran Hub Tower. Once inside the Tower they steadily made it to the reactor core, picking up survivors of other units en route. Once they reached the reactor core, Sabre Force along with Sergeant Nathan Hale overcame Chimeran defenses and destroyed the core, liberating Britain from the Chimera.
