Its split trail enables the U. S. army’s new experimental 144-millimeter “T-3" howitzer to fire almost straight up, higher than any other army weapon. It sends a ninety-five pound shell over a range of 10,000 yards. The gun was put in action for the first time recently on the artillery range at Fort Bragg, N. C. The front of its carriage is raised on a jack to form a tripod for firing.
