As in wars prior, artillery of WW1 was a prerequisite for battlefield success. Artillery proved the number one threat to infantry and tanks alike and came in several light, medium and heavy forms. Additionally, field guns served in the direct line-of-sight role while mortars and howitzers allowed for indirect fire support. Any gun type fired shrapnel or high-explosive rounds at range - the most popular field gun proving to be the 75mm French Model 1897 which brought about use of an integrated recoil mechanism allowing for successive shots without the gun having to be relaid. However, the stalemate that was trench warfare soon limited the benefits of line-of-sight weapons until the breakthroughs later in the war.
