DUTIES AND RESPONSIBILITES
WHY ARE NCOS RECEIVING NCOPD ON A WEAPON SYSTEM
THAT WILL NOT BE OUR ASSIGNED WEAPON?

• WE ARE LEADERS! If our soldiers are tasked to
  operate this piece of equipment, we must be
  proficient enough to train them on this piece of
  equipment!

• BE, KNOW, DO! If we are to BE a leader of
  soldiers, we need to KNOW how to operate this
  piece of equipment, clear malfunctions, train
  soldiers on its use, PMCS, clear malfunctions,
  set emplacements, dig fighting positions, give
  fire commands, determine sectors, complete range
  card. We must be able to DO all of the above
  in order to lead by examplewe cant tell a
  soldier to perform a task we cannot perform
  ourselves!

HISTORY OF THE MK 19

• Development began in 1963 with a preliminary
  version that was a hand cranked grenade launcher
  called the MK 18. In 1966 the MK 19 Mod 0 was
  developed, however the MOD 0 was not reliable or
  safe to be placed in the Armys inventory.
  Improvements in 1971 led to the Navys adoption
  of the MOD 1 in 1972 and worked well during the
  Vietnam conflict. In 1976, the weapon was
  redesigned as the MK 19 MOD 3, that was adopted
  for Army use in 1983. The Army has expanded the
  use of the MK 19 for tactical defense,
  retrograde, patrolling, rear area security, MOUT,
  and Spec Ops.

INTRODUCTION

• THE MK 19 SUPPORTS THE SOLDIER IN BOTH THE
  OFFENSE AND DEFENSE. IT GIVES THE UNIT A HEAVY
  VOLUME OF CLOSE, ACCURATE, AND CONTINUOUS FIRE.
  IT CAN ALSO BE USED TO
• Protect motor movements, assembly areas and
  supply trains
• Defend against hovering rotary aircraft
• Destroy lightly armored vehicles
• Fire on suspected enemy positions
• Provide high volumes of fire into an engagement
  area
• Cover obstacles
• Provide indirect fires from defilade positions.

10
INTRODUCTION
The MK 19 is an air-cooled, blowback-operated
machine gun, with five major assemblies that is
belt-fed through the left side of the weapon by a
disintegrating metallic link belt.
11
INTRODUCTION
Leaf type rear sight mounted on a spring dovetail
base, which should be folded forward to a
horizontal position when the weapon is moved the
range increment of 100 meters from 300 to 1500m.
Range changes by slide release or the elevation
wheel slide release for major changes in
elevation slide wheel for fine adjustments. Rear
sight adjusts for windage, turning the windage
screws right or left equals a 1-mil change.
12
INTRODUCTION
13
INTRODUCTION
The HEDP (High Explosive, dual purpose) M430
cartridge, joined with M16A2 links is the
standard round for the MK 19. The impact-type
round penetrates 2 inches of steel armor at a
0-degree obliquity and inflicts personnel
casualties in the target area. The two HE (High
Explosive) cartridges inflict personnel
casualties in the target area with ground burst
effects. HE M383 and M383E1 are packed 50 per
box. The M385 practice rounds are joined by M16A1
or M16A2 links in 50 rounds per box. M992 dummy
cartridges are joined with M16A2 links with a 10
round belt used to check weapon function for crew
training.

• Perform after PMCS and report deficiencies to the
  armorer
• Clean and lubricate the MK 19 before storage

45
OPERATION AND FUNCTION
Malfunctions and corrections NOTE Defective
ammo nor soldier head-space-and-timing is
considered a weapon malfunction. The two
malfunctions are sluggish gun, and runaway
gun.
Sluggish Gun Caused by excessive friction from
dirt, carbon build-up, lack of lubrication, or
burred parts. Conduct a proper PMCS, replace worn
and or damaged parts, as necessary. Runaway
Gun Weapon continues to fire after the trigger
has been released. Caused by worn parts or short
recoil of the bolt assembly. If ammo is not low
and gun is in the free mode, keep rounds on
target until all the rounds on the belt have been
fired. If mounted on tripod with TE, hold the
grip with one hand, press the charger handle
locks and lower one charging handle. This
interrupts the cycle causing the weapon to cease
firing.
46
OPERATION AND FUNCTION
IMMEDIATE ACTION In the event of a stoppage in
the MK 19, take immediate action recharge it and
try to fire once. REMEDIAL ACTION A stoppage is
any interruption in the cycle of operation caused
by faulty action of the weapon or ammunition.
Take remedial action if immediate action does not
end the stoppage. (1) Unload and clear MK
19. (2) Inspect the weapon and ammo to find the
cause of stoppage. CORRECTIVE ACTION Take
corrective action to correct the stoppage one the
cause has been found. If possible, correct the
cause of the stoppage, reload and try to fire the
weapon. If it still does not fire, or cannot be
repaired at the operator level contact the unit
armorer.
47
CREW DRILLS
Crew drills build precision, speed, skill and
teamwork in checking equipment, placing the MK 19
into and taking it out of action, and moving it
to a new position. Precisionthe main goal is
achieved by following prescribed procedures.
Speed, skill, and teamwork grow with practice.
During the crew drill, all oral and visual
signals are repeated. Once crew members can
perform their duties well, they rotate to allow
each member of the crew to learn the duties of
the others. The ground mounted MK 19 has three
crew members the gunner, the assistant gunner,
and the ammo bearer. A vehicle assigned to the
crew carries the ammo and equipment to the firing
position. The terrain and enemy situation dictate
how close the vehicle may be brought to the
firing position. To assist your soldiers, you
may follow the step by step guidelines found in
Chapter 4, of FM 23-27

MARKSMANSHIP FIRING POSITIONS

• FIGHTING POSITIONS
• Position MK 19 in the center of the assigned
  sector of fire. Mark the position of the tripod
  legs and trace the outline of the firing
  platform, which will be dug approximately 3
  deep.
• Dig the position in the shape of an L around the
  firing platform. Chest deep and wide enough to
  allow for operation of equipment throughout the
  sector of fire. Position can be made so gunner
  can fire from the kneeling position by digging
  the desired depth behind gun.
• Use dirt from the hole to build flank parapets
  18 thick. Dig the ammo storage area into the
  left wall of the L and close to the ground.
• Make sure wall behind is sloped to allow for
  entrance and exit.

65
MARKSMANSHIP FIRING POSITIONS

TRAVERSING BAR AND TE MECHANISM
TRAVERSING BAR AND TE MECHANISM The TE
mechanism is for use to engage preselected target
areas at night or during degraded conditions.
Record elevation readings from the traversing bar
and TE mechanism. All readings are in mils.
Zero the TE (1) Hold the TE so that the
traversing handwheel is on your left as you look
at it. Turn the traversing handwheel toward you
until it stops. Loosen the locking nut slightly.
Align the 0 on the scale with the 0 on the
elevation screw yoke. Hold the scale with the 0s
aligned, and tighten the locking nut. Make sure
the 0s stay aligned. Turn the traversing
handwheel two complete revolutions away from you,
or count 50 clicks away from you.

TRAVERSING BAR AND TE MECHANISM
Place weapon and choose sector of fire. Pick up
the rear legs of the tripod and shift the MK 19
until the muzzle points to the center of the
sector of fire stamp feet and place sandbags on
the legs for stability. Obtain and record
direction readings to all targets within the
sector of fire, by loosening the traversing slide
lock and sliding along until the muzzle is
centered on a point target. Lock in place and
read the direction from the scale on the
traversing barif the left edge of the traversing
bar does not read exactly on a 5-mil tick mark,
move the left edge back to the next smaller mil
reading. Record readings as right or left of
muzzle center, then measure the width of the
target in mils using the traversing handwheel to
move across the target.
