The anti-aircraft defenses of Poland were based upon three types of weapons: the heavy machine gun, the medium range 40 mm cannon, and the 75 mm anti-aircraft gun. The 152 heavy anti-aircraft guns were formed into 42 batteries, 40 of which were, in turn, combined into 10 independent heavy flak battalions.

The 326 40 mm guns were formed into thirty-five 4-gun batteries and ninety- three 2-gun sections. Thirty of the 40 mm batteries were attached to the active infantry divisions, two flak batteries were stationed on the Hel Peninsula, two flak batteries were assigned to the motorized brigades, and one flak battery was attached to the "Prusy" Army as an independent command. Eleven of the 40 mm sections were attached to the cavalry brigades, and 82 sections were independent units stationed for local defense at various locations around the country. The heavy machine guns were primarily dual purpose 7.92 mm guns assigned to various formations to provide them some measure of anti-aircraft protection. The only exception was a battalion of eighteen 13.2 mm Hotchkiss guns which were assigned to the "Coastal" Operational Group, and stationed at Gdynia and on the Hel Peninsula.
