If there be no officer of the guard, the adjutant inspects the guard. A noncommissioned officer commanding the guard or commanding a platoon of the guard takes post as prescribed for an officer.

d. (1) The inspection ended, the adjutant places himself about 30 paces in front of and facing the center of the guard, and draws saber. The new officer of the day takes post in front of and facing the center of the guard, about 30 paces in rear of the adjutant. The old officer of the day takes post 3 paces to the right of and 1 pace to the rear of the new officer of the day. The officers of the day, without drawing saber, take the position of parade rest with the adjutant and resume the attention with him. The commander of the guard takes his post in front of the guard. If he be an officer he draws saber with the adjutant and comes to the order.

(2) The adjutant then commands: 1. Parade, 2. Rest, 3. SOUND OFF, and comes to the order and parade rest.

(3) The band, playing, passes to the left of the line between the officer of the guard and the adjutant, and back to its post on the right, when it halts and ceases playing.

(4) The adjutant then comes to attention, carries saber and commands: 1. Guard, 2. ATTENTION, 3. Close ranks, 4. MARCH.

(5) The ranks are closed without command from platoon leaders.

(6) The adjutant then commands: 1. Present, 2. ARMS, faces toward the new officer of the day, salutes, and then reports: "Sir, the guard is formed." The new officer of the day, after the adjutant has reported, returns the salute with the hand and directs the adjutant: "March the guard in review, Sir," or "March the guard to its post, Sir."

(7) The adjutant carries saber, faces about and brings the guard to the order. When directed to march the guard to its post, the adjutant repeats the command and the commander of the guard marches the guard directly to the guardhouse in the most practical manner. The band and field music are dismissed. Otherwise the adjutant commands: 1. (At trail), platoons (or guard), right, 2. MARCH, 3. Guard, 4. HALT.

(8) At the second command the guard executes the movement and the band turns to the right and places itself 12 paces in front of the first platoon. The band halts with the guard at the fourth command.

(9) The adjutant places himself 6 paces from the left and 3 paces in front of the front rank of the guard; the sergeant major, 6 paces from the left flank of the front rank of the second platoon, or 6 paces from the left flank of the front rank of the guard when there is no division into platoons.

(10) The adjutant then commands: 1. Pass in review, 2. Forward, 3. MARCH. (11) The guard moves in quick time, with the band playing, past the officer of the day, marching and saluting according to the principles of review. The adjutant and the commander of the guard salute together, leaders of platoons, and drum major salute with their units, and the sergeant major salutes with the unit by which he is marching.

(12) The band having passed the officer of the day, turns to the left out of the column, places itself opposite and facing him at a distance of 20 paces from where the left flank of the guard passes, and continues to play until the guard leaves the parade ground. The field music detaches itself from the band when the latter turns out of the column, and, remaining in front of the guard, commences to play when the band

ceases.

(13) Having passed 12 paces beyond the officer of the day, the adjutant halts. The sergeant major halts abreast of the adjutant and 1 pace to his left. The adju

tant, and sergeant major if so armed, then return saber, face each other, salute, and retire. The commander of the guard then commands: 1. Platoons right by squads (or Right by squads), 2. MARCH, and marches the guard to its post.

(14) The officers of the day face toward each other and salute. The old officer of the day turns over the orders to the new officer of the day.

(15) The new officer of the day returns with one hand salute the salutes of the commander of the guard and the adjutant.

e. The new bugler of the guard forms and continues with the field music of the band and marches with the field music to the guardhouse. When the new guard is divided into reliefs the bugler relieves the old bugler of the guard and with him reports to the new officer of the day for inspection and instruction.

3. Informal guard mounting.— -a. Informal guard mounting is held on the parade ground of the organization from which the guard is detailed, or, if the guard is detailed from more than one organization, at such place as the commanding officer may direct.

b. At assembly, and at command of the first sergeant, the detail for guard falls in on the company parade ground. The first sergeant verifies the detail, inspects the dress and general appearance, and replaces any man unfit for guard duty. He then turns the detail over to the commander of the detail and retires. The detail commander then reports his detail to the commander of the guard at the point designated for the assembly.

c. (1) The commander of the guard causes the guard to form as a platoon, and takes post 3 paces in front of the center of the guard, and faces to the front, with the junior officers of the guard 3 paces to his left. The officer of the day takes his place 15 paces in front of and facing the center of the guard, and commands: 1. Officer (or officers) and noncommissioned officers, 2. Front and center, 3. MARCH. The officers and noncommissioned officers then take their positions, are assigned and sent to their posts as prescribed in formal guard mounting. The officer of the day directs: "Prepare for inspection." The officer commanding the guard faces about and commands: 1. Open ranks, 2. MARCH. He then proceeds to the right flank of the guard, verifies the alignment, commands: FRONT, and takes post 3 paces in front of the right guide facing to the left and commands: PREPARE FOR INSPECTION, and faces to the front remaining at carry saber.

(2) The officer of the day then inspects the guard according to the principles of company, inspection, sees to its fitness for the duty for which the guard is detailed, and selects the necessary orderlies and color sentinels. The men found unfit for guard are returned to quarters and replaced by suitable substitutes. This fact is reported by the officer of the day to the adjutant immediately after guard mounting.

(3) When the inspection is completed, the officer of the day resumes his position and directs the commander of the guard to march the guard to its post. Ranks are closed and the guard marched, without music, in the most practicable manner.

(4) The new bugler of the guard forms in the line of file closers at the formation of the guard detail and reports to the officer of the day as prescribed for formal guard mounting.

(5) When a noncommissioned officer commands the guard, the officer of the day gives the commands for opening and closing ranks and verifies the alignment.

(6) When the guard is commanded by a noncommissioned officer he takes post as prescribed for an officer, except that in marching to the front and center he takes post on the right of the line of noncommissioned officers. At the command of the officer of the day he returns to the post prescribed for the officer 3 paces in front of the right guide.

4. March of new guard to guardhouse.-a. As the new guard approaches the guardhouse, the old guard is formed in line, with its field music 3 paces to its right and on the same line. When the field music at the head of the new guard arrives opposite the old guard's left, the commander of the new guard commands: 1. Eyes, 2. RIGHT (and the commander of the old guard commands: 1. Present, 2. ARMS.) Commanders of both guards exchange salutes. The new guard marches in quick time past the front of the old guard.

b. When the commander of the new guard is opposite the field music of the old guard, he commands: FRONT. (The commander of the old guard commands: 1. Order, 2. ARMS, as soon as the new guard has cleared the front of the old guard.) c. The field music, having marched 3 paces beyond the field music of the old guard, changes direction to the right, and followed by the guard, changes direction to the left when on line with the old guard. The changes of direction are without command. The commander of the new guard halts on the line established by the old guard, allows his guard to march past him, halts it in line 3 paces to the right of the field music of the old guard, and dresses his guard to the left. The field music of the new guard halts 3 paces to the right of the new guard on the line of its front rank.

5. Presenting old and new guards.-a. After the new guard is dressed, the commander of each guard (in front of and facing its center, commands: 1. Present, 2. ARMS, resumes his front), salutes the other guard (carries saber, faces toward his guard and commands: 1. Order, 2. ARMS).

b. If the guard is commanded by a noncommissioned officer, he takes post and executes the facings as prescribed for an officer and renders the proper salute, rifle, saber or hand, according to his equipment.

6. Presenting new guard to officer of the day. After the new guard has saluted the old guard, it is presented by its commander to its officer of the day. If there be but one officer of the day present, or if one officer acts in the capacity of the old and new officer of the day, each guard is presented to him by its commander.

7. Salutes by guard.-a. If other persons entitled to a salute approach, each commander of the guard brings his own guard to attention if not already at attention. The senior commander of the two guards then commands: 1. Old and new guards, 2. Present, 3 ARMS.

b. The junior salutes at the command present, given by the senior. After the salute has been acknowledged, the senior brings both guards to the order.

8. Dispositions of new guard.-a. After the salutes have been acknowledged by the officers of the day, each guard is brought to the order by its commander. The commander of the new guard then directs the orderly or orderlies to fall out and report, and causes bayonets to be fixed, if so ordered by the commanding officer.

Bayonets are not thereafter unfixed during the tour except in route marches, while the guard is actually marching, or when especially directed by the commanding officer.

b. The commander of the new guard then causes to fall out members of the guard for detached posts, places them under charge of the proper noncommissioned officers and divides the guard into three reliefs. When the guard consists of troops of different arms combined, the men are assigned to reliefs, under rules prescribed by the commanding officer, so that a fair division of duty may be assured.

9. Relief by new guard.--The sentinels and detachments of the old guard are at once relieved by members of the new guard. The two guards stand at ease or at rest while these changes are being made. The commander of the old guard transmits to the commander of the new guard all his orders, instructions, and information concerning the guard and its duties. The commander of the new guard then takes possession of the guardhouse and verifies the articles charged to the guard.

10. Dismissing old guard. If considerable time is required to bring in that portion of the old guard still on post, the commanding officer may direct that, as soon as the orders and property are turned over to the new guard, the portion of the old guard at the guardhouse be marched off and dismissed. In such cases the remaining detachment or detachments of the old guard are inspected by the commander of the new guard when they reach the guardhouse. The latter directs the senior noncommissioned officer present to march these detachments off and dismiss them in the prescribed manner. For taking over prisoners, conducting relief of sentinels, etc., see TR 135-15, Interior Guard Duty, Part One,. this chapter.

11. When field music may be dispensed with.-In bad weather, at night, after long marches, or when the guard is very small, the field music may be dispensed with.

1. General description.-The Browning automatic rifle, model of 1918, is an air-cooled, gas-operated, magazine-fed, shoulder weapon. It has no special cooling system, the barrel being exposed to the air, and the hand of the firer being protected on the underside of the barrel by a large wooden forearm. Care must be taken to avoid touching the barrel during firing. The rifle is operated by the power furnished by expanding powder gases following ignition of the cartridge. These powder gases expand through a port in the barrel and act upon the head of a piston, driving it to the rear. During rearward movement the processes of unlocking, extraction, ejection, and compression of the recoil spring are effected; during the forward movement, feeding, locking, and igniting the cartridges are accomplished. The rifle is fed from a magazine having a capacity of 20 cartridges. This rifle can be fired effectively from all positions prescribed in TR 150-30, part two, this chapter. It is capable of being fired at the rate of 150 rounds per minute, semiautomatic. The rate of fire, however, which gives the best results in the normal case is 40 to 60 shots per minute, semiautomatic.
