补充资料：机枪
| 机枪 machine gun 带有两脚架、枪架或枪座，能实施连发射击的自动枪械。机枪以杀伤有生目标为主，也可以射击地面、水面或空中的薄壁装甲目标，或压制敌火力点。通常分为轻机枪、重机枪、通用机枪和大口径机枪 。根据装备对象，又分为野战机枪（含高射机枪）、车载机枪（含坦克机枪）、航空机枪和舰用机枪。轻机枪装有两脚架，重量较轻，携行方便。战斗射速一般为80～150发／分，有效射程500～800米。重机枪装有稳固的枪架，射击精度较好，能长时间连续射击，战斗射速为200～300发／分，有效射程平射为800～1000米，高射为500米。通用机枪，亦称两用机枪，以两脚架支撑可当轻机枪用，装在枪架上可当重机枪用。大口径机枪，口径一般在12毫米以上，可高射2000米内的空中目标 、地面薄壁装甲目标和火力点。
