The 127th Light Mechanized Infantry Division is the primary maneuver element of the 54th Group Army in the Jinan Military Region. The 127th Light Mobile Mechanized Infantry Division is one of the most famous and best-equipped PLA formations. Its three main regiments, the 371st, 379th, and 380th, are all Red Army Regiments. The 371st regiment is the famed Ye Ting independent regiment, a nationalist armored train unit that was once commanded by Dr SunYat-Sen, with Zhou Enlai as it’s political commissar during the Republican Revolution of 1911. The "Iron Army" title was an honor for its Armored Train roots. It also acted as vanguard in the battle to seize the Luding Bridge during the Long March.
