The series is at times intense and has some realistic battle sequences. Not much gore, some blood is seen in gunfights. Some hand to hand combat with bloody detail.
Lots of battles with blood, not much gore is shown though, there is one scene where a man is walking through a trench with some dead bloodied bodies. Similar to 1917, but not as graphic a Saving Private Ryan.
Some battles show people with missing legs and ligaments.
