Choosing

Site
When you are choosing a site for an exercise
in
which
a
Simulator
will be
used,
you
need to take into account two things:
o
Are the receiver/detectors
deployed
the
way
they

tlefield?
o
Are the receiver/detectors and transmitter deployed so that the
signal
from the transmitter can reach all receiver/detectors and cause
the
detectors to go into alarm?

The M43A1 Detector is designed to provide a tactical unit

members will need to survive during a chemical attack:
o
Detection of a toxic agent cloud, and
o
Early warning to troops in the protected
position.
On a battlefield, good judgement in deploying detectors can mean the difference
between timely detection of an attack or massive numbers of chemical casualties.
The M43A1 Detector can be remoted up to 400 meters from the M42 Alarm. The greater

far out, there is a chance of an agent cloud slipping behind them. To decide the
actual location of detectors, you must consider the chemical agent delivery threat,
the terrain, and the state of preparedness of friendly troops.
Usually, the Simulator will be use
d
with four detectors. On the battlefield, when
four detectors (as opposed to six)
are used to protect a position, the detectors
are shifted into the wind whenever
the wind direction changes more than 20 degrees.
This ensures that the detectors are
always upwind of the unit or units to be
protected.
When choosing a site for placement of receiver/detectors during an exercise, remem-
detectors should be deployed according to wind direction,
ber one important thing:
not according to the direction of the enemy.
The receiver/detectors should be within line-of-sight of the transmitter, and there
should be as few buildings, trees, or other obstacles separating transmitter and
receiver/detectors as possible.
