How many times have you used one of
these to call for fire support to protect your signal site from
"The AN/PRC-77 set was an
updated version of the PRC-25. Specifications and accessories for
the two are nearly identical. Differences in design were internal.
The AN/PRC-77 includes a solid stare power amp that did away with
the PRC-25 2DF4 power amplifier tube in the final stage. Its
completely solid state design made it more reliable and reduced
power requirements. Filters were added to reduce interference. The
PRC-77 also includes the capability to work with X-mode speech
encryption, for greater communications security. The PRC-77 could be
used for secure voice communications with the addition of NSA
designed COMSEC boxes (KY-38 and later KY-57)."
bet you can't guess what this is?
It's the KOI-18. The KOI-18 is a battery
operated Key Tape Reader that converts physical key tape into an
electronic format for use in the KYK-13, KYX-15, and the AN/CYZ-10
devices. It is capable of accepting both paper and mylar tapes. The
KOl-18 has no storage capability.

another for you. You can tell what it is by looking at it. But what
was its designation?
It's a WWII Cable Splicer RL-31. Below
you can see one mounted on the back of a jeep. The cable
reel is mounted in the RL-31 reel unit, a foldable framework which
could be employed on the ground or mounted in two different ways on
a jeep: suspended off the rear at a 45 degree angle, as in the
picture, or straddling the back wall of the jeep. The unit could
also be set on the ground.
about this one? This should be easy for you.
In the latter stages of the Korean war, the Army
saw a need for more tactical radios for the Infantry, Rangers and
Special Forces. The AN/PRC126 Field radio was one solution that is
still in use today. Typically it is issued along with a AN/PRC126
Field Radio Pouch, and a AN/PRC126 "Handset Scarf" tactical vest.
The AN/PRC-126 is a short range, handheld tactical radio for use
primarily at the squad/platoon level. It consists of a lightweight,
militarized transceiver providing two-way, voice-communications. The
radio covers the frequency range of 30-87.975 megahertz. Its nominal
range for reliable communications over rolling, slightly wooded
terrain is 3,000 meters. The radio is capable of interoperating with
the AN/VRC-12, AN/PRC-77 and SINCGARS families of radios in the
fixed frequency mode. The AN/PRC-126 enables small unit leaders to
adequately control the activities of subordinate elements in
carrying out the unit's mission. Over its years of use, many a life
has been saved because of this baby, and many a firefight won. While
found way down the food chain from tactical satellite
communications, tropospheric radio terminals, and the rest, it
nevertheless still plays a critical role in creating a fully
integrated Command, Control, Communications, Computers and
Intelligence (C(4)I) system.
One more picture for you to guess at....
Ever seen one of these? After a while they all
start to look alike, don't they? This unit is the AN/GRC-160. You're
looking at two different views of the same unit, one for portable
use, the other for built-in applications.
The AN/GRC-160 was often used in anti-armor
companies to coordinate heavy anti-armor fire support.
And finally... a few thoughts to help
place your time in the service in perspective...
