I'm still learning Korean, but I think 거리 means "Street" and 길 is more like the "way" (when you're lost and asking for the directions for example). But I'm not sure, so if anybody can correct me...[emoji] Hope it helps ! Btw, hi fellow army.[emoji]

길 means "path" including all kinds of path like street, road, track.. 거리 (same to 길거리) means "path crowded with people or vehicles" and is usually used as the meaning of "street"
