A single-casemate pillbox in the forests north-east of Osowiec Fortress.
One of the smallest structures built on the Molotov Line, housing a 7,62 mm Maxim heavy machine gun. It was equipped with an optic scope which greatly increased accuracy within its 2,2 km ( 1,37 mile) effective range of fire.
Remnants of an earth embankment covering the structure are still visible. Back in 1941 it was completely hidden under a pile of stones and earth. With grass and scrub growing on the roof, much like on the photo, this small killer was hardly visible to the enemy.
