The Chinese-American Composite Wing’s unique composition was not always readily accepted. As the 3^rd Bomb Squadron prepared to enter combat in Burma, a serious conflict arose. Maj. R. L. Patterson, in command of the 83^rd Bomb Squadron, 12^th Bomb Group, was distrustful of the abilities of the recently-arrived and biracial 3^rd Squadron. Before allowing the mixed Chinese-American crews to "tack onto" his planes for missions, he insisted that 3^rd Squadron airmen fly a practice formation flight with the 83^rd to demonstrate their readiness for combat. The following day, Capt. Raymond L. Hodges Jr. and "his Chinese boys, Lts. Tung and Yen" flew follow element to the 83^rd Squadron's lead element. "Our boys assembled and tacked on much quicker than the 83^rd, who flew an extremely wide pattern,” according to a later report. However, a mechanical failure forced the lead plane down, leaving Patterson unsatisfied, so he demanded a second practice flight. Once again, the Chinese pilots "made a wonderful showing" and Patterson called off the flight.

In late 1944, it became clear to observers that Japanese forces coming from the north were moving toward a junction with troops advancing westward toward Nanning from Canton.  Col. John A. Dunning, in command of the 5^th Fighter Group at Chihkiang (Zhijiang), put in a request for four B-25s with crews to run missions in close conjunction with his "Flying Hatchet" fighters to resist the enemy drive. His pilots had found that daytime targets were scarce and scattered because the enemy was moving troops and supplies primarily at night, so that was when he intended to strike. Called "Task Force 34," its participants were detached from the 3^rd and 4^th Bomb Squadrons, and the majority of their missions were night single-plane strikes at river, rail, and road traffic in the Hsiang Valley and from Hankow to Kweilin. Many of them were accomplished without moonlight. So successful were these “moonless-night missions” that they became a specialty of Task Force 34.
