美國士兵是以火力班組為單位行動的，基本上就是幾隻步槍、兩挺機槍、兩隻精準步槍。首先步槍兵的標配為m16a4，發射模式為單發或是三點連射。除了自動步槍之外還會配發一支m9半自動手槍，主要用於主武器沒有彈藥之後，利用手槍邊打邊撤的。

機槍兵配發的為一支m249或是m60機槍，前者為5.56mm後者為7.62mm，為了減輕機槍兵的自身負荷，機槍兵一般情況下是不配備副武器的，畢竟多帶一支手槍也要帶相應的彈藥，這樣會導致機槍兵本身攜帶機槍子彈減少，為後期火力壓制創在不利局面。

精準射手一般會配發一支半自動或栓動步槍，作為精準狙殺。為了彌補其自身的近距離火力不足，通常會裝備一支能夠全自動擊發的手槍，很多時候為格洛克手槍，在敵人接近時可以全自動擊發，讓敵人在最短的時間吃到一梭子子彈。

你這還不如問美軍現役單兵武器有那些比較好...懶得一個個說了，直接列，因為太多了
