Any foreign weapon may be useful to troops seeking to better their tactical position, but weapons in which an enemy has a qualitative lead are especially valuable. Above is seen a common or garden variety of old German 88 being used by U.S. troops; below, a German 170-mm gun used by the British.
An excellent example of such initiative took place during the recent war in Europe. General Patton's Third Army, faced in the fall and early winter of 1944 with a stringent ammunition shortage, refurbished and put into action serviceable items of captured artillery. On 2 November 1944, one corps—the XX—was employing 39 such pieces, classed as follows: four 76.2-mm Soviet guns, ten 88-mm German guns, eight 100-mm fortress guns, six 105-mm German howitzers, two 122-mm Soviet guns, six 150-mm German howitzers, and three 155-mm French howitzers. Up to that date, this corps had fired 30,920 rounds of ammunition weighing 660 tons and valued at $702,391. For the week ending on 29 October of that year, 80 percent of the artillery ammunition fired by the XX Corps had been captured from the Germans. One time-on-target mission fired on a German troop concentration at Amanvillers was executed by U.S. tank destroyers, 90-mm antiaircraft guns, 155-mm M1 howitzers, and by German 105-mm gun howitzers, German 88's, Soviet and French Schneider 155-mm howitzers. The Soviet weapons, and those of the French, had been seized from Allied forces earlier in the war, and had been recaptured by the Third Army.
