Military Sangar and Observation Posts
Observation Posts are usually vital necessities
for force protection. An observation post consists of a small enclosed
space. Observers in a Sangar are vulnerable to rocket, mortar fire and
small arms fire. The walls of these observation posts are made of steel
or, preferably, reinforced concrete with a composite style liner.
Outside these walls a yielding steel mesh rocket screen is needed
to catch, disrupt or detonate any incoming projectiles launched at the
Sangar. Inside these walls a standoff is needed to protect the
occupants from any sudden bulge or residual fragments.
The roof
of the sangar should preferably be reinforced concrete with a composite
style liner held on a Defence-Structures
frame. Above this, with a standoff, should be a yielding steel mesh
mortar screen. Below the roof should be a liner at a standoff to
protect the observers from sudden bulges in the roof or residual
fragments.
In the walls of the observation post are fitted
embrasures. These are formed holes in the reinforced concrete wall with
steel backing plates. They are equipped with sliding steel closers or
with sliding polycarbonate panels.
The entrance to the Sangar, if at ground level, is
a steel door with lesser protection, from the "safe side", though this
may be protected by cover
from view screens and/or rocket
screens, depending on the threat. If the OP is to be elevated
it should be built on a Defence-Structures
tower. Access is then from the underside through a trap door. The sides
of the tower need protection of rocket
screens and walls, or at the least cover from view screens
around the access ladder or stair.
The rocket screen in front of the embrasure may
need drop-gates to allow improved view but rapid closure.
