From the outstanding Internet web site War is Boring a reference to a movie the topic of which was the German Storm Troop of the Great War [WW1].
In German with subtitles in English, re-mastered and edited more or less in entirety. Forgotten for many decades but now available on You Tube and can be viewed for free as an example of historical cinematic excellence..
"‘Shock Troop 1917’ Is a Brutal War Film … From 1934"
"The movie was popular with German nationalists"
"Hans Zöberlein’s 1934 feature film Stoßtrupp 1917 — Shock Troop 1917, in English — depicts German storm troopers fighting on the Western Front during World War I, slogging from the Aisne to Champagne to Cambrai."
German storm troops. Lots of hand grenades. That man in the front is wearing a Red Cross armband and yet carrying a grenade! Storm troops often had to advance through an area which only a few minutes earlier had been subjected to an artillery barrage delivering poison gas on target!
"The film is deeply nationalistic — and was hugely popular in its time. Compared to contemporary films such as All Quiet on the Western Front and West Front, Shock Troop 1917 is less pacifist in tone"
"All Quiet on the Western Front" pacifist and anti-war. "Shock Troop" the opposite but not so excessively so. Combat as it was during that period and as presented and depicted quite realistic for the time!!
