Also another movie that I would recommend is Hacksaw Ridge (2016). It is the most self-sacrificing and Christian of the war movies about someone risking their lives, in a Japanese strong-hold to rescue wounded soldiers and he went into the war without holding a gun because it was against his faith to kill people. He went to war to heal people rather than kill, and it's based on a true story.
I watched this, along with the two movies I had recommended last year. I'm glad you've made this thread. I've sort of backslid this month on my commitment to watch war movies. I've tried watching The Kill Team (2019), but it had too much swearing on it, but it might be good for someone else. Another movie I watched last month was called "King's Speech" (2010) which portrays King George V at the beginning of WW2 when he had to make a radio announcement about the war.
Other movies in my "to watch" list is
1) Aftermath (2017) - this deals with the clean-up after WW2 where Americans occupy homes once lived in by Germans and Germans are resentful of them. I've watched the first 20 min of this last year, but perhaps in this themed war-month, I'll view the rest of it.
2) Band of Brothers -- TV series of WW2 - focuses on East Company, 506 Regiment of the 101 Airborne division from 1942 to the end of WW2. - this is on my watch-list, but now that it's brought to light again, I may watch it before the month is over, at least the first few episodes.
3) They Shall not Grow Old (2018), this movie has actual footage from WW1 with some narrations from veterans who were alive during that time.
4) The Tuskegee Airmen (1995) -- African American pilots fighting during WW2.
5) Official Secrets (2019) - on my watchlist - Iraq War is in its subject matter.
6) Midway (2019) -- the battle of Midway - watched it earlier this year but it didn't make a strong impression as a war movie, don't hear its being referenced much anyway. Not sure if I'll re-watch this.
7) Franz (2016) - some type of story based after WW1. Rather boring, but may try to view this again.
The idea of having a war-movie themed month (couldn't possibly watch everything in one day, so I expand it to Remembrance Month - you know, just like you have Black History month in February, because you can't take everything in within one day. You have to really get into it to have a virtual mental experience like you are a participant in a historical war to imagine how it would be like being a solider, or how older veterans today would look in the prime of their lives looking at some of these Black and White war footages, etc....
I leave more specific movies dealing with Nazi Germany, the Holocaust and the Jewish experience for January as there are also a number of movies dealing with those themes. The last time I really spend a month looking at those types of movies was back in January 2011, but I visited Israel and its Holocaust museum in 2010 so that may have accounted for the additional interest in those types of movies at the time.
Of everything I can think of, I think Winston Churchill's speech "fight on the beaches", sort of stands-out as the British nation was steering into the face of a certain doom after the evacuation, and that speech, I could imagine, was really inspiring at that time. This was brilliantly placed at the end of the Dunkirk 2017 movie and was touching when the soldiers read about this in the newspaper.
One of the lines in the Dunkirk movie which were touching is how a soldier apologized for losing the war, and how a friendly and blind person told him, You've stayed alive, that's good enough....or something like that. Seeing those civilian boats come to the rescue at the beech when it appeared all hope was lost was also a moment that brought tears to my eyes.
I leave this with a youtube clip of Churchill's speech:
