Despite prompting by the news media, Stilwell never complained about his treatment by Washington or by Chiang. He later served as Commander of Army Ground Forces, U.S. Tenth Army Commander in the last few days of the Battle of Okinawa in 1945, and as U.S. Sixth Army Commander.

Among his recommendations was the establishment of a combined arms force to conduct extended service tests of new weapons and equipment and then formulate doctrine for its use, and the abolition of specialized anti-tank units.

In particular, he called for "guided interceptor missiles, dispatched in accordance with electronically computed data obtained from radar detection stations."
