FM 3-06.11 Combined arms operations in urban terrain. 28 feb 2002

(5) To fire an 84-mm Carl Gustaf recoilless rifle, the AT4, or SMAW-D from inside a
room, the following safety precautions must be taken (Figure 7-5).
(a) The building should be of a sturdy construction.
(b) The ceiling should be at least 7 feet high with loose plaster or ceiling boards
removed.
(c) The floor size should be at least 15 feet by 12 feet. (The larger the room, the
better.)
(d) At least 20 square feet of ventilation (room openings) should exist to the rear or
side of the weapon. An open 7- by 3-foot door would provide minimum ventilation.
(e) All glass should be removed from windows and small, loose objects removed
from the room.
(f) Floors should be wet to prevent dust and dirt from blowing around and obscuring
the gunner’s vision.
(g) All personnel in the room should be forward of the rear of the weapon.
(h) All personnel in the room should wear helmets, body armor, ballistic eye
protection, and earplugs.
(i) If the gunner is firing from the prone position, his lower body must be
perpendicular to the bore of the weapon or the blast could cause injury to his legs.
Т.е. комната 4,5 на 3,6 метра, вентиляция 2,1 на 0,9 метра (открытая дверь), потолок 2 метра. Это минимум. Мне кажется, что такой минимум есть очень много где.

На Википедии без ссылок утверждают, что
The use of the recoilless firing system allowed the Carl Gustav to use ammunition containing considerably more propellant, firing its rounds at 290 m/s, as opposed to about 105 m/s for the Panzerschreck and Bazooka and about 75 m/s for the PIAT.
Думаю, желающим будет не трудно это проверить. Сгорает, ЕМНИП, всё в трубе.

Можно ли теперь предположить, что использование РПГ-2 в условиях описаных выше не доставит стрелку излишнего дискомфорта?
