The majority of foreign countries have adopted pack transport for their machine guns. It is desirable with infantry and absolutely essential with cavalry. A suitable saddle is, of course, indispensable, and strong spiral springs to the hooks which hold the gun and tripod on either side will entirely prevent horses from straining their backs when galloping across country or jumping obstacles with the guns. These hooks must be leather-covered and made to fit the gun exactly, and, in order to do away with the present cumbersome straps and buckles, they should have a hinged attachment to close over the gun and lock automatically in such a way as to admit of its being opened by a single movement when it is required to dismount the gun. The Swiss and the Americans have permanently adopted pack transport for the machine guns with their cavalry, which are able to accompany them over any country without detriment to either horses or guns; and in the American army the average time for a well-trained cavalry machine-gun detachment to go into action front, from mounted formation, unpack, and set up the guns, load, aim, and open fire, is 25 seconds; while at the departmental meeting for 1908 the machine guns of the 10th Cavalry, from the halt in line, moved forward in section column at a gallop for 200 yards and went into action and fired a blank shot in 31 seconds.[A]
This brings us to the second factor—Visibility.
