The 6 inch howitzer, model of 1908 was the standard American heavy howitzer before World War I. Forty-two of these weapons had been produced before 1917, and all were employed within the US for training in that war. Although this weapon appears in World War I-era tables of organization and equipment, for combat use in France the Canon de 155 C mle 1917 Schneider was purchased, and variants of this remained the standard weapon of this class until early World War II. All surviving weapons were retired during the 1920s.
