In addition to this, provisions are made for a limited number of trailers for use in carrying light guns at high speed behind motor These vehicles. trailers are rubber tired and for high-speed condi- tions; the complete gun, with carriage, may be placed on this trailer instead of being transported on its own wheels. The recent struggle in Europe brought about problems which heretofore have never existed in warfare; and to meet these changes have been made in every arm of the service, but the greatest and 75-MILLIMETER GUN CARRIAGE MOUNTED ON A 3-INCH FIELD GUN TRAILER.
Trench mortars. GUNS. THEIR FUNCTIONS AND CONSTRUCTION. " gun consists of a metal tube, closed at one end, of sufficient strength to resist the pressure of the expanding gases, in which is placed a projectile designed to move through the tube. The force expanding gases acting on the base of the projectile causes on its flight in a definite direction. When the charge is the ignited, explosion or rapid combustion of the powder gives rise its by decomposition to a large amount of gas, which tends to expand, and to occupy a space greater than that in which the powder was of the it to start originally contained; consequently, it exerts a pressure in all direc- and the energy developed is utilized in forcing the projectile from the tube.
Briefly, the foregoing describes the fundamentals of anti-aircraft artillery fire-control methods. Being the most precise form of gunnery, anti-aircraft artillery involves material capable of the highest degree of facility and accuracy in the automatic measurement of deflections and the maneuvering of its gun-laying mechanisms in order that effective fire may be conducted against a target whose movements are subject to such large displacements. ACCOMPANYING VEHICLES. In addition to the piece itself, a number of vehicles are necessary in batteries, sectors, and regimental organizations of field artillerj7 for maneuvering and serving the piece.
