2. All six gun positions are at present equipped with coastal guns of Soviet
manufacture. The sea in front of the shore batteries is deep and the coast line
is steep so that all six gun positions are on elevated terrain*
3o These battery positions have been constructed from one master plan; however, the
dimensions vary according to the terrain. (A, sketch sho.ng_the positions and 25X1

shore battery positions is composed of a forward observation post, a command
post located between the observation post and the gun emplacements, and the -

reinforced-concrete emplacements which are connected by passage-ways., each one
being connected:: to the command post by telephone, (A sketch showing the gun
emplacement, top view is included as

each guns traverse was 360-
degrees. The guns are mounted on a turntable which is 60 or 70 cm. above the
floor level. The floor level, in turn,, is about 2.5 meters below the ground
level. The center of the gun emplacement is uncovered., while adjoining personnel
shelters and ammunition storage areas,, and the connecting passage-ways are covered
by a reinforced concrete roof. Each gun position has personnel shelters in which
two men can be comfortably accomodated. In March 1951s the guns were being put
in position.
U. Each shore battery position has two ammunition storage shelters approximately 150
to 200 meters apart and about 100 to 150 meters behind the gun emplacements.
(A sketch showing a horizontal cross-section of the shelter is included as Appendix
E, on page 8). The shelters are sunk into the ground to a depth of 3,5 meters and
are built of reinforced concrete; the walls and roof are 70 centimeters thick$
the shelters are camouflaged with grass. In March 19518 both of the shelters at
Nesebur were filled with ammunition.

The gun positions were constructed during 1911 and 19142., of reinforced concrete,
in the shape of a small circula-z? house covered by a four-sided., pyramidal tile
roof. For camouflage purposes, dummy windows were drawn; the gun embrasures
are actually below the d and just above the ground level. (A sketch
