In 1939 Poland had 102 FT tanks, including training ones. They had not much combat value by then.*
45 were used in three companies (111, 112, 113), in five-tank platoons. Latter two were used in defence of Brzesc fortress (Brest-on-the-Bug), among others, blocking its gate.*

20 tanks were used on railway chassis as armoured draisines of Polish armoured trains - two per a train. They could also fight on the ground.*
