I made a DDay film in arma 2 a few years back with the i44 mod. I wanted to see how it would look in Arma 3 so I made another using the Iron Front mod.
In some ways it happened so long ago it seems abstract now. The closest the D-day invasion touched me that I know of is through an uncle who himself was too young to fight in WW2. He said he was watching a newsreel of the invasion in the theater and recognized one of the men landing on the beach that was killed during the invasion.
