text: An S.F.14Z stereo 10x magnification binocular sight (for the commander) and an E.M.34 coincidence-type rangefinder with 11x magnification meant this gun was able to deliver calibrated fire out to a range of 4,000 m. Firing at a 2.5 m x 2 m target under test conditions at 1,000 m, this gun delivered 100% accuracy, dropping to 87% at 2,000 m and 53% at 3,000 m, although the E.M.2 rangefinder was able to range targets out as far as 10,000 m.
