Asymmetric warfare is when two sides in a conflict don't have the same type of weapons and tactics. In other words, one side has a big advantage over the other. For example, one side might have a lot of tanks and fighter jets, while the other only has guns and grenades. In order for the weaker side to win, they need to find a way to use their weapons and skills in a way that will even the playing field. This can mean taking advantage of any terrain or hiding spots, developing different tactics, or using guerilla warfare.
