For firing blank it is fitted with an attachment called the “drill and blank-fire attachment.” (_c_) _The Colt Automatic._--Calibre ·3 in., and takes the service rifle bullet. The gun is fed by means of a cartridge belt, and fires 400 rounds a minute. The weight is 40 lb., and the gun is mounted either on a tripod mounting or a wheeled carriage. A “silencer” for the Maxim was tested in March, 1909, and the results compared with those obtained from the gun without the silencer. As regards accuracy of fire there was nothing to choose between the two. The silencer, however, reduced the noise to that of a ·22 in. long cartridge, and when used at night the flash was entirely obliterated. ORGANISATION.--_Infantry._--One battalion in each regiment has a machine-gun platoon consisting of 1 sergeant, 2 corporals, and 18 privates, and 2 guns. _Cavalry._--In a regiment of 3 squadrons, 1 squadron has a machine-gun platoon of 3 corporals and 18 privates. AUSTRIA GUN.--In 1907 after prolonged trial the Austrians definitely adopted the Schwarzlose. It is a very simple weapon and very reliable, firing 375 rounds per minute from a tripod mounting. ORGANISATION.--A section of machine guns is attached to each regiment of cavalry and infantry; there are also mountain companies of machine guns. With infantry the section consists of 2 guns; 10,000 rounds are carried per machine gun. The detachment consists of 14 men per gun, 7 for actually working the gun and 7 to lead the horses. There are 7 horses to each gun, of which 1 carries the gun and 500 rounds, 5 carry from 1,500 to 2,000 rounds each, and 1 carries the shields. There is also a spare horse. For hand transport one man carries 2 belts of 250 cartridges, another the gun and 1 belt, a third the mounting and 1 belt, a fourth 2 belts, a fifth the water-jacket, etc. The shields are left on the horse. It will be seen that when the machine gun is taken forward in this way it has ready for immediate use 1,500 rounds. With cavalry the section consists of 4 guns without shields. On account of the great independence of cavalry, the machine guns have with them 15,000 rounds each, of which 5,000 are on pack-animals and 10,000 in wagons. These wagons usually march in rear of the column. The detachment, which is all mounted, consists of 9 men per gun with 4 pack-horses (1 for the gun and 3 for ammunition). Hand transport is provided for as with the infantry machine guns. The mountain machine-gun company consists of 3 officers and 64 other ranks. There are 4 guns carried on pack-horses, with 2 pack-horses per gun for ammunition (4,000 rounds per gun).
