None.

War-related violence, torture and death are talked about.

There are some footage of war-related shooting, bombing and burning, but nothing too bad or disturbing is shown, except from a dead man in a car that is briefly shown in part 3.

Some mild language.

Barely any to no visible smoking.

Some of the war-related stuff that is talked about can be intense. Same can be said about some of the footage being shown throughout.
