In the first episode a man has his torso blown off by a shell. We see him fall from behind and then we see all his organs. Very gory and graphic. Later on in the episode, there is a fight between some German and British soldiers in a tunnel. Soldiers are shot with little blood. One character is shot with quite a lot of blood seen afterwards.
In the second episode, a battle occurs. We see a soldier get caught on some barbed wire and then get shot several times in slow motion, with a bloody mist after every bullet penetrates his body. Quite graphic. Later on there is an explosion in a tunnel which results in several characters dying with two survivors. One is seriously injured. (Fairly gory.)
