2. Giving amphibious functions firefighting unit is not justified. The layout of the pontoons requires the application of manual force. The capacity of the pontoons to extinguish small fires. In operation afloat machine can overcome water obstacles only with gently sloping banks and a reliable ground. When driving in dense forest on the twisting roads of the pontoons will be damaged on closely spaced trees. This will eliminate the possibility of filling them with water and works to extinguish the fire. Overcoming water obstacles with pierced pontoons fire unit can sink.

3. The unreliability of the catapult, designed for emission soderjasim debris tree roots soil can stop catapult due to jamming of the working body.

4. The base chassis Assembly, as follows from the description and drawing, refers to the cars light weight category, as evidenced by giving the unit the floating properties. With the lack of weight, these machines have low permeability in the dense forest. The experience of Krasnoyarsk Vniipomleshoza confirms the need to use for extinguishing forest fires machines manufactured on the basis of the tanks (Vladimir Sokolov, "the Tanks are coming.. .wedge", journal Air-Siberia", 14 (104), July 1999).
