Buuxi weedhan soo socota: Mashruuca lagu horumarinayo qoriga taangiga ee cabirkiisu yahay 105mm (4.1 in) ayaa markii ugu horreysay la bilaabay intii lagu jiray WWII si ay ula tartamaan taangiyada Jarmalka ee aadka loo hubeeyay. Ka dib duulaankii Yurub, Waaxda Hubka waxay aaminsanaayeen in loo baahan yahay taangiyo aad u gaashaaman oo qalabaysan hub awood leh si ay u jabiyaan aagagga deyrka leh. Waxay soo jeediyeen in nooca M6 ee taangiyada culus ee hadda jira ay noqdaan kuwo gaashaaman oo ay ku rakibaan 105mm T5E1 cusub. T1E1s-kan wax laga beddelay oo leh qoryaha T5E1 ee munaaradaha la ballaariyay (oo laga soo qaatay mashruuca T29 ee la soo jeediyay) ayaa loo magacaabay M6A2E1. Mashruuca M6A2E1 ma uusan socon markii Eisenhower uu diiday isticmaalkiisa
Yurub bishii Ogosto 18, 1944, laakiin laba M6A2E1s <unk> oo aan lahayn gaashaaman kordhay <unk> ayaa loo adeegsaday in lagu tijaabiyo hubka iyo qoryaha loogu talagalay T29 Taangiga culus ee soo socda.
