As of September 1939, Poland had 38 cavalry regiments and 34 squadrons used for reconnaissance by units not possessing light tank companies. Poland's large cavalry force was organized into 11 independent brigades of three or four regiments each. The strength of a brigade was:

Cavalry Brigade	Three Regt	Four Regt
Men	6,143	7,184
Light MG	89	104
Heavy MG	81	95
Antitank Rifles	66	78
Mortars	11	11
75mm Guns	12	16
40mm AA Guns	2	2
Antitank Guns	18	22
Light Tanks/Armored Cars	24	24

There were also 12 squadrons of KOP cavalry, which formed improvised regiments upon mobilization. Polish cavalry was equipped with lighter versions of standard infantry weapons and, despite romantic accounts of cavalry charges, was to operate as mobile infantry and fight dismounted.

Poland planned to motorize at least five cavalry brigades by 1942.
