Name:13 cm KwK 55 L/60 + 7.5 cm KwK 44 L/36 auf Panzerjäger Tiger Ausf. C (Sd.Kfz. 186/2)Nickname: JagdTiger Zwilling (“Twin JagdTiger”)---Fictional BackstoryDevelopment (Late 1944 – Early 1945)By the end of 1944, Germany’s armoured corps faced a grim reality: Soviet IS-2 mod. 1944 tanks were appearing in greater numbers, and British Centurions loomed on the horizon.
