Here’s a fantastic video of the Polish Army’s equipment (taken sometime pre-September 1939) showing lots of great shots of things like Bofors 37mm AT & 40mm AA Guns, both types of tanks (the Vickers and the 7TP), Armoured Cars, Infantry & HMG teams, various motorcycles, trucks, half-tracks and fully-tracked tractors (e.g. C2P / C4P / C7P), Skoda 220mm Heavy Howitzers and an Armoured Train!
