军粮 (jūn liáng) literally combines 军 (jūn), meaning 'military' or 'army', and 粮 (liáng), meaning 'grain' or 'food supply'. Together, it refers specifically to food provisions officially issued to soldiers for sustenance during service, training, or deployment. Unlike everyday meals, 军粮 emphasizes standardization, portability, long shelf life, and nutritional adequacy under field conditions.

This term is used historically and contemporarily in official, journalistic, and military contexts — for example, when discussing logistics, wartime preparations, or disaster relief operations where troops distribute emergency rations. It carries a formal, institutional tone and is rarely used metaphorically or in casual speech. While 粮 alone can refer broadly to food or grain, adding 军 specifies the military’s organized provisioning system, distinguishing it from civilian food supplies or personal snacks.
