102 additional track links were installed. The installation took 2.5 hours.
Based on conducted trials, the following conclusions can be made.
Additional track links for the T-26 significantly increase the performance of the T-26 in swamps, especially on mossy terrain. The design of the additional track links is simple and can be built in any battalion workshop. Additional track links can be carried on the front armour, which requires special clips. In addition to their advantages, the swamp tracks have the following drawbacks:
- Installation takes a long time (2.5 hours for a crew of 3).
- Movement of the tank with additional track links is only possible on soft terrain.
- It is necessary to increase the robustness of the material of the tracks in order to prevent the possibility of cracks when hitting hard terrain.
- Tanks drove to their destination without additional track links.
- Trial areas were chosen inside the swamp, and the direction of movement was marked with posts.
- A tractor with a winch was used to evacuate stuck tanks.
- The tank without additional track links was hooked up to the winch (the cable was extended) in the chosen direction until the tracks started slipping and the tank became bogged down. The tank was dragged out of the swamp by the winch.
- Additional tracks were installed, and the tank moved out along the old trail (without the winch).
- Swamp #1: peat bog, covered in moss and rare sedge. During movement, the upper layer sends waves 1.5-2 meters in diameter. A metal rod 24 mm in diameter and 2.2 meters in length that falls freely from a height of 0.5 meters descends to a depth of 30-40 cm. With effort from one hand, the rod descends to a depth of 0.8-1.0 meters. The swamp has "windows" of water. For a human, the swamp is passable in all directions, with sinking to a depth of 0.3 to 0.4 meters.
- Swamp #2: covered in thick reeds and sedge. A human sinks to a depth of 0.4-0.5 meters. The surface has a 400-500 mm layer of water. There are no mounds or trees. 60-70 meters from the shore, the reeds vanish, and the upper layer becomes green moss with cranberries. There is no water on the surface. A human does not sink, but his movement creates a wave 2-2.5 meters in diameter. A metallic rod falling freely from a height of 0.5 meters descends to 60-80 cm and sinks completely (2.2 meters) from the effort of one hand."
