Though encumbered by a busy schedule, Pauling was eager to support his country's armed forces, accepting virtually any viable project offered him. A few such projects even relied on his skills outside of the sciences. During the war, the U.S. military developed a significant interest in German weapons engineering, doing its best to capture, study and sometimes replicate enemy designs. Many of the German weapons included design elements virtually unknown to U.S.-based weapons-makers. As a result, the Navy, Army, and members of government-funded research programs felt it was important to learn as much as possible about German military research since World War I. In 1945, as part of this effort, General-major Uto Gallwitz was asked to translate Die Geschützladung from German to English. Linus Pauling, as a member of the OSRD and a capable German-speaker, was asked to oversee the translation. The work resulted in the publication of German Powder Development Between 1918 and 1942, a Bureau of Ordnance text. Though not widely recognized as one of his achievements, Pauling's work on the project greatly expanded the United States' understanding of German artillery.

While much of his propellant work was done early in the 1940s, Pauling continued to work intermittently on ballistics problems throughout the war. Division 8 of the OSRD continued to provide him with updates on the state of the program until its closure and reassignment. In August 1945, he received his final report from the division which explained the effect of Japanese surrender on arms manufacturing and outlined the post-war goals of the U.S. ballistics program.

Ultimately, Pauling's research team, in conjunction with the various other personnel associated with the ballistics committee, successfully engineered several new powders which proved to be both more stable and more powerful than their predecessors. Their contributions to the war effort, while impossible to measure accurately, undoubtedly proved crucial to American assaults on armored vehicles and entrenched strongholds across Europe, Africa, and the Pacific islands. In 1945 Pauling received a certificate from the War Department, signed by the Secretary of War, the Chief of Ordnance, and the Commanding General of the Army Service Forces. The award was presented "For outstanding services rendered in time of war to the Rocket Development Program of the Ordnance Department." Pauling received a similar award, a week later, from the United States Navy Bureau of Ordnance.
