He served under his old superior until March 1944 and took part in the training of new marine officers.

When 22nd Marines were deactivated at the end of March 1946, Larson remained in China and was transferred to Beiping, where he was appointed commanding officer of the 5th Marine Regiment. He was also promoted to the rank of colonel at the same time. In this capacity, he supervised the removal of Marine units of his regiment from China, and the handover of some areas to Nationalist Chinese government.^[7]

The members of the group were Thomas J. Coolley, John P. Condon, Joseph N. Renner, Carson A. Roberts, Samuel R. Shaw, George R. E. Shell, Eustace R. Smoak, William J. Van Ryzin, and Richard G.
