Classes Of Fire With Respect To The Ground
Fire with respect to the TARGET includes Frontal Fire - when the long axis of the beaten zone is at a right angle to the front of the target. Simply stated, that means when firing directly into the front of a target. Flanking Fire - when delivered directly against the flank of a target. Oblique Fire - when the long axis of the beaten zone is at an angle other than a right angle to the front of the target. Enfilade Fire - when the long axis of the beaten zone coincides or nearly coincides with...
Fundamentals And Firing Techniques
Each member of the machinegun crew must be trained in standard methods of applying fire with the machinegun, both as a member of the crew and as a gunner. The easiest and quickest means of delivering fire with the gun mounted on its bipod, tripod, or vehicular mount is by alining the sights of the gun on the target and properly applying fire. This technique of fire is called DIRECT LAY. At times, techniques of fire other than direct lay are more effective- When delivering fire in the assault,...
Applying The Fingermeasurement Method
A fire command is given to deliver effective fire on a target quickly and without confusion. When the leader decides to engage a target which is not obvious to the gunners, he must provide them with the information they need to effectively engage the target. He must alert the crews, and give a target direction, description, and range the method of fire and the command to fire. There are initial fire commands and subsequent fire commands. Initial fire commands are given to begin firing at a...
Engaging Hardtoidentfy Targets With A Reference Point Within The Target Area
Deep targets are engaged with searching fire. When range is announced, it is given to the midpoint of the target. Machineguns in Pairs. The point of initial lay on a deep target for both guns is on the midpoint, which is also the point of division. Normally, the number 1 gun has the near half and the number 2 gun the far half- Since enfilade fire is being delivered, it is not necessary to adjust on the midpoint of the target, because the long beaten zone will compensate for any range errors....
Ordinate
H - MAXIMUM ORDINATE HIGHEST POINT OF TRAJECTORY Maximum Ordinate. This is the highest point the trajectory reaches between the muzzle of the gun and the base of the target. It always occurs at a point approximately two thirds of the distance from the gun to the target. The maximum ordinate increases as the range increases. Cone of Fire This is the pattern formed by the different trajectories in each burst as they travel downrange. When several rounds are fired in a burst from a machinegun,...

The BFA is adjusted by organizational maintenance personnel, using the following procedure Insure that the large nut on the front of the BFA is tight. Unscrew the orifice tube with a pair of large pliers. Fit it into the barrel until the clamp will barely start over the front sight. With the BFA installed on the barrel, pinch the clamp tightly behind the wingnut with the fingers and rap the top front of the BFA above the large nut with a machinegun combination tool the clamp will snap into...
Blank Firing Attachment
The BFA must be adjusted to fit the machinegun barrel. The orifice tube fits inside the flash suppressor, flush against the gun muzzle and flush with the forward end of the flash suppressor. The BFA is clamped tightly to the front sight. When properly adjusted, it will fit snugly against the muzzle, thus preventing the escape of gas during firing. When the BFA is manufactured, the distance the orifice tube screws into the restricter bushing is fixed and fitted by ''staking'' the restricter...

Operation and Cycle of Functioning
The M60 machinegun is loaded, fired, unloaded, and cleared from the open-bolt position. The safety lever must be placed on FIRE before the bolt can be pulled to the rear. Before using ammunition, insure that It is free of dirt and corrosion. 9 The double link is at the opening end of the bandoleer. Place the safety lever on FIRE. Pull the bolt to the rear by the cocking handle with the palm facing UP. When the bolt is held to the rear by the sear, manually return the cocking handle to the...
CLASSES OF FiRE WITH RESPECT TO THE TARGET
Fire with respect to the GUN includes Fixed Fire - that delivered against a stationary point target when the depth and width of the beaten zone will cover the target. Traversing Fire - that distributed in width by successive changes in direction. With the tripod-mounted gun, the changes are made in 2- to 6-mil increments on the traversing handwheel between bursts. If denser fire is needed, a 2-mil change in direction will cause an overlap of beaten zones to insure complete coverage of the...
Disassembly and Assembly
The M60 machinegun can be disassembled and assembled without special tools or equipment. With the exception of the barrel group and the cocking handle, general disassembly requires only a cartridge or other pointed object. Detailed disassembly requires a combination tool. In disassembly, as each part is removed, it should be placed on a clean, flat surface such as a table, shelter half, or disassembly mat This makes it easy to keep track of parts, and it aids in their assembly since the parts...
Introduction
The 7.62-rnm M60 machinegun supports the rifleman in both offense and defense. It provides the heavy volume of close and continuous fire he needs to accomplish his mission. It can engage targets beyond the capability of individual weapons, with controlled and accurate fire. The long-range, close defensive, and final protective fires delivered by the M60 form an integral part of a unit's defensive fires. The M60 is a general purpose machinegun. It is used on a bipod, a tripod, or a vehicular...

Danger Space
Therefore, not all the distance between the gun and the target is danger space. Machinegun fire is classified with respect to the GROUND, the TARGET, and the GUN. Fire with respect to the GROUND includes Grazing Fire - when the center of the cone of fire does not rise more than 1 meter above the ground. When firing over level or uniformly sloping terrain, a maximum of 600 meters of grazing fire can be obtained. Plunging Fire - when danger space is practically confined to the beaten zone....

Relative Size And Shape Of Beaten Zone
Beaten Zone. This is the pattern formed by the rounds within the cone of fire striking the ground or the target. The size and shape of the beaten zone changes when the range to the target changes or when the machinegun is fired into different types of terrain. On uniformly sloping or level terrain, the beaten zone is long and narrow. As the range to the target increases, the beaten zone becomes shorter and wider. When fire is delivered into terrain sloping down and away from the gun, the beaten...
Range Card With Final Protective Line
Predetermined targets in the secondary sector are sketched on the range card, and ranges to these targets are recorded below the sketches but not in the data section. Field expedients should be used for targets in the secondary sector, since the gun must be employed in the bipod role. NOTE A PDF is used when grazing fire can not be obtained, i.e.,whenthegun is located on rough, hilly, or broken terrain. The PDF is directed at the most likely enemy avenue of approach.
