Lehké opevnění vz. 37 "řopík"

Ostrava embedded ŘOPík.

Lightweight fortification model 37 (lightweight fortification of a new type, popularly Řopík) is a reinforced concrete fortress of light fortification built in the framework of the construction of the Czechoslovak fortification. The folk designation "řopík" originated in the second half of the 1930s according to the abbreviation ŘOP (Directorate of Fortification Works). ROP was controlled and commissioned by external construction companies. In the thirties of the 20th century, on the basis of the changed political situation in neighboring Germany, the then Czechoslovak government decided on the method of possible defense of the republic. In the framework of the great modernization of the army, the construction of a permanent border fortification was also adopted. Objects of the crew strength in the number of men were organizationally included in the so-called light fortifications. Initially, a lightweight model 36 fortification was built, and its construction was later stopped and replaced with a more refined lightweight fortification model 37. The Land Military Headquarters, which controlled the construction of the model 36, replaced the newly appointed ROP body in the case of model 37.
