1M 249 SAW
2TASK, CONDITIONS, STANDARDS
- TASK To familiarize the soldier with the M249
Squad Automatic Weapon (SAW). - CONDITION Given a block of instructions, M249
SAW, and motivation. - STANDARD To disassemble, separate into proper
grouping, and reassemble the M249 SAW correctly
with no deficiencies.
3M 249 SAW
- Features The Squad Automatic Weapon (SAW), or
5.56mm M249 is an individually portable, gas
operated, magazine or disintegrating metallic
link-belt fed, light machine gun with fixed
headspace and quick change barrel feature. The
M249 engages point targets out to 800 meters,
firing the improved NATO standard 5.56mm
cartridge.The SAW forms the basis of firepower
for the fire team. The gunner has the option of
using 30-round M16 magazines or linked ammunition
from pre-loaded 200-round plastic magazines. The
gunner's basic load is 600 rounds of linked
ammunition.
4M 249 SAW
- Background The SAW was developed through an
initially Army-led research and development
effort and eventually a Joint NDO program in the
late 1970s/early 1980s to restore sustained and
accurate automatic weapons fire to the fire team
and squad. When actually fielded in the
mid-1980s, the SAW was issued as a one-for-one
replacement for the designated "automatic rifle"
(M16A1) in the Fire Team. In this regard, the SAW
filled the void created by the retirement of the
Browning Automatic Rifle (BAR) during the 1950s
because interim automatic weapons (e.g.
M-14E2/M16A1) had failed as viable "base of fire"
weapons.
5M 249 SAW
- Background Cont. -
- Early in the SAW's fielding, the Army identified
the need for a Product Improvement Program (PIP)
to enhance the weapon. This effort resulted in a
"PIP kit" which modifies the barrel, handguard,
stock, pistol grip, buffer, and sights. - The M249 machine gun is an ideal complementary
weapon system for the infantry squad platoon. It
is light enough to be carried and operated by one
man, and can be fired from the hip in an assault,
even when loaded with a 200-round ammunition box.
The barrel change facility ensures that it can
continue to fire for long periods. The US Army
has conducted strenuous trials on the M249 MG,
showing that this weapon has a reliability factor
that is well above that of most other small arms
weapon systems. Today, the US Army and Marine
Corps utilize the license-produced M249 SAW.
