Tiny training guns, equipped with sighting devices identical with those on their full-size prototypes, offer the equivalent of regular field practice for artillerymen. One-inch steel balls are the projectiles fired by twenty-two caliber cartridges, “short” or “long” blanks being used, depending on the range and elevation desired. The target is a midget village built in a sand pile across the armory floor. An observer stands back of each gunner, noting the result through field glasses and reporting the information to a board marker. Shots that fall short are indicated by a minus sign, and those over the mark score a plus. Gunners watch the “scoreboard” and correct their fire to make hits. When firing is over, a clean-up man scoops the steel balls from the sand with a special rake. The salvaged ammunition is then put away for the next practice session.
