Input: Context: War film is a film genre concerned with warfare, typically about naval, air, or land battles, with combat scenes central to the drama.

Themes explored include combat, survival and escape, sacrifice, the futility and inhumanity of battle, the effects of war on society, and the moral and human issues raised by war.
