TKS

[citation needed] 575 TK/TKS tankettes formed the bulk of the Polish armoured forces before the outbreak of war.

Their small size suited them for reconnaissance and infantry support, but with their light armament of a single machine gun they stood no chance in combat against German tanks, except against the Panzer I.

[3][4] After the conquest of Poland, captured tankettes were used by the German army in various support roles, mostly for training, security duties or as artillery tractors.

[6] A smaller Polish force retreated to (then neutral) Hungary from the German and Soviet troops occupying Poland.

[7] Experimental models: A list of registration numbers[1] (might be incomplete): There are only two fully operational TKS tankettes and one TK-3 surviving.
