Ministry of Military Affairs. It consisted of elite soldiers from all parts of Poland. Initially ''KOP'' comprised 6 brigades and 5 regiments, each guarding part of the borders with the Soviet Union. ''KOP'' ceased to exist with the
fall of Poland in September 1939. In 1940, some of its former officers formed an underground armed resistance organization fighting against the German occupiers, the Komenda Obrońców Polski.

The soldiers of KOP were trained to combine the tactics of the army, police forces and border guards. They guarded the borders actively, not only by patrols, but also through reconnaissance, ambushes, provocation and intelligence gathering. During the first year of its existence, the KOP arrested more than 5,000 people trying to cross the border illegally. In addition, 89 armed skirmishes were fought, mainly against the bandits from the

Piłsudski's reforms (1929–35)
In July 1929, the Border Defence Corps was reorganised. Six additional regiments were created, and all the existing units were renamed. Each brigade was attached to part of the Polish border which was further divided into battalion areas organised around small forts along the border. In turn, each of the battalions commanded several smaller strongholds and outposts organised by companies. All the rear troops (including the engineers, artillery and cavalry) formed the second line of the defence and were to be used as a mobile
reserve. The brigades were given new names, after the area they were stationed in:

Hel, Poland. Although most of the units were later reconstructed at the eastern border, their combat value was much lower. The recruits lacked experience and training and the units of KOP were deprived of almost all heavy weaponry.
On August 30 the KOP was formally
mobilised. General
Wilhelm Orlik-Rückemann became its commander. According to the Polish plans for the forthcoming war, the KOP was to become the backbone of reserve divisions formed behind the Polish lines.
