陆军英语说作 "land army" 或 "ground forces"。这两个词的来源都很明显："land" 指的是陆地，"army" 指的是军队，而 "ground forces" 则是指陆地作战部队。

一些英文例句及其中文翻译如下：

The land army was deployed to the border to defend against the enemy invasion. (陆军被部署到边境，以抵御敌人的入侵。)

The ground forces were well-equipped and trained for urban warfare. (陆军装备精良，并经过了城市战争的训练。)

The land army played a crucial role in the victory of the war. (陆军在战争胜利中扮演了至关重要的角色。)
