More than one couple is found kissing in their tent, sometimes removing clothing but nothing is seen and it is stopped before anything goes too far.

Non. (Unless you count a brief kiss as sexual content)

There is VERY strong scenes of injury detail including gun-shot wounds, severed limbs, body parts ripped open and apart, gangrene and of surgery.

It is VERY bloody throughout the series.

There is one scene where a nurse is slapped by a patient who is in a state of mental unwellness and paranoid.

There is regular conversation of troop-advancement in war

One use of 'Fucking' and one use of 'Shit' in the final episode (EP-6)

There is no profanity in any of the first 5 episodes

Regular scenes of smoking and alcohol consumption. Use of drugs in medicines such as heroin liquid for cold symptoms, and either for anesthetic.

Some will find the injury/gory scenes very upsetting and not advisable to watch while eating as it is very graphic.

Some may also find the general story (WWI) upsetting aswell as the losses the nurses have to go through.
