(105-MM Howitzer Ml02 Towed, 105PM Howitzer bl01- series towed, 155MM Howitzer M14Al Towed, 155MM Howitzer M109A1 self- propelled, 105MM Howitzer XM204 Towed, 155MM Howitzer XM198 Towed). The trainer will provide year-around training of section personnel in standard direct fi-re tec
44、hniques while engaging both stationary and moving targets on a scale range. The trainer will allow realistic firing exercises to be conducted in garrison, without having to move howitzers to a iive firing range and without: expending either sub caliber or service ammunition. 6.2 Ordering Data.- Proc
