In tropical areas, dampness and fungus growth will materially reduce the effective range
of field wire lines. Therefore, construction techniques may vary from the norm. Selection of the best
route for a wire line is extremely important to construction and maintenance. Ground reconnaissance is
more effective than aerial reconnaissance, because dense jungle growth hides trails and roads from aerial
observation.

In many instances, it may not be possible to avoid areas that have been chemically or
biologically contaminated. In any case, personnel will be required to wear the mission oriented
protection posture (MOPP) gear to accomplish their mission. The requirement to wear MOPP gear will
significantly affect the rate at which work can be performed. MOPP gear causes physiological as well
as psychological degradation.

Voice communications while wearing the mask becomes difficult. Hearing is
impaired. Field of vision is narrowed because of the mask and identification of personnel is difficult.

If equipment is available, go out and practice installing the wire line using as many of the means
of construction as possible. It is imperative that you learn these techniques because they will save you
time and maintenance work later on. Make sure you complete the line and install another TA-312/PT on
the other end. Be sure to check the line for errors and tagging and be sure enough slack is placed in the
line where needed.
