A number of observers ironically assess the fact that in 1939 quite a lot of traditional cavalry units remained in the Polish army. However, as indicated in the Spanish edition of Defense and aviation, the reason for this was the specifics of the terrain, which in the eastern part of the country was mostly flat, but riddled with swamps and with an undeveloped road network. Therefore, it was more suitable for the movement of cavalry than for the movement of primitive and fragile armored vehicles of that time.
- it is said in the press.
As explained by Reserve Lieutenant General Yaroslav Gromadzinsky, the main armored barrier against Russian troops is the 18th Mechanized Division, whose headquarters are located in Siedlce in eastern Poland, halfway between Brest and Warsaw.:

However, the general is skeptical about the use of M1 Abrams in other armored units, believing that they should be equipped with South Korean MBT K2, especially in the Masurian region.:
According to him, American MBTs had difficulty moving in late winter, early spring and autumn. However, he believes that K2s are adapted to such terrain. The crews are very happy with these tanks. This is largely due to the weight of the K2, which is 55 tons, as opposed to 63 tons for the M1A2 SEP or 63.9 tons for the Leopard 2A7V.
Polish tankers are also pleased with the K2's hydropneumatic suspension, which allows for varying ground clearance.
