美国一直很关注如何发挥身管火炮在未来战争中作用的问题。在阿富汗战争和伊拉克战争中,美军对于105毫米和155毫米火炮在轻、中、重型部队作战行动中的适用性等问题有不同看法。 2002年,在轻型部队部署于阿富汗参加“持久自由”行动之初,美军决定不携带火炮,只依靠重型迫击炮和空中火力支援。然而,英国首先表示反对,其他盟国也不同意,最终,美国陆军也感觉此决定欠妥。 The United States has always been very much concerned about how to play the role of barrel guns in future wars. In the war on Afghanistan and the war in Iraq, the U.S. military held different opinions on the applicability of 105mm and 155mm artillery to combat operations of light, medium and heavy units. In 2002, at the beginning of the deployment of light troops to Afghanistan for “protracted freedom”, the U.S. military decided not to carry artillery but instead rely only on heavy mortar and air-fire support. However, the United Kingdom first expressed its opposition and the other allies did not agree. At the end of the day, the U.S. Army also felt that this decision was defective.
