US tanks could be M24 Chaffee (mostly with steel tracks), M26, M26A1, and M45 versions of the Pershing, M46 and M46A1 Patton. M4A3 (76) and (105) Shermans, mostly with HVSS suspension, were widely used by US and Canadian units. Howitzer armed versions were usually fitted with dozer blades as well, and used as de facto engineer vehicles. US Army used M32B1 recovery vehices, and Marines had some M32A1B3 versions. Marines also had their unique double barreled flamethrower Shermans, which combined a 105 mm howitzer and a coaxial flame gun. M19 antiaircraft tanks were also used. M7B1 and M7B2 Priest self propelled howitzers and M40 "Long Tom" self propelled guns were widely used. M47 Patton was not deployed to Korea until after the fighting. British forces used Churchill Crocodile flame tanks, Cromwell Mk VII recon tanks and Centurion Mk 3 main battle tanks. North Korean People's Army had a variety of T-34-85 tanks, both WW2 and postwar production models, and lots of SU-76M assault artillery vehicles. Gerald Owens
