With the appearance of the Rifts, the efficacy of the Proletarian Hemotype serum has been greatly magnified. Taking advantage of this and stolen Axis research Soviet Science has created an astonishing triumph to counter the Axis’ dread Shreckwulfen; a new breed of soldier, the Ursus Infantry. Bonding humanity to the formidable Siberian Brown Bear has resulted in an augmented, monstrous soldier. Little is more symbolic of the Soviet Union’s bold embrace of the Rift than the Ursus.

Deployed in small squads, they engage in brutal close-quarters combat, ripping their way through enemy lines and leaving carnage in their wake. Even the most advanced Rift-enhanced units are hard pressed to resist their physical and psychological challenge.
