Star
Parachute Round.
This round is white impact or bar
alloy aluminum with black markings. It is used for illumination and signals
and is lighter and more accurate than comparable handheld signal rounds. The
parachute attached to the round deploys upon ejection to lower the candle at
7 feet per second. The candle burns for about 40 seconds. A raised letter on
the top of the round denotes the color of the parachute.


 
White
Star Cluster Round.
This round is white impact or
bar aluminum alloy with black markings. The attached plastic ogive has five
raised dots for night identification. The round is used for illumination or
signals. It is lighter and more accurate than comparable handheld signal
rounds. The individual stars burn for about 7 seconds during free fall.


  
Ground
Marker Round.
This round is light green impact
aluminum with black markings. It is used for aerial identification and for
marking the location of soldiers on the ground. It arms between 15 and 45
meters. If a fuze fails to function on impact, the output mixture provided
in the front end of the delay casing backs up the impact feature. The color
of the ogive indicates the color of the smoke.


 
Practice

Used for practice, this round is blue zinc
or aluminum with white markings. It produces a yellow or orange signature on
impact, arms between 14 and 27 meters, and has a danger radius of 20 meters.

it is a multipurpose round, it is most effective for riot control and in
MOUT. It arms between 10 and 30 meters and produces a white cloud of CS gas
on impact.


  
Buckshot

This round is olive drab with black
markings. Though it is a multipurpose round, it is most effective in thick
vegetated areas or for room clearing. Inside it has at least 2,000 pellets,
which cast a cone of fire 30 meters wide and 30 meters high and travel at
269 meters per second. Be sure to aim buckshot rounds at the foot of the
target. The round has no mechanical-type fuse.
