The Operations Room YouTube Channel will be covering the four separate Battles that comprise the Battle of Leyte Gulf which itself is arguably the largest naval battle in history depending on your metrics.

Falcon's Fighter Tales who covers aviation, aircraft and airpower and air force historical topics and the like with his cute twinky anime avatar, is now covering the totally innocuous Usean anti-asteroid weapon known as Stonehenge. Which as anyone who is familiar with history knows is a giant network of railguns known as Titan Guns that became the most feared air defense weapon in history.

Up until then anyways...
After covering the Second World War, week by week, seventy nine years after the events took place and with the War in Europe over (for the most part) the channel with its combined million plus subscribers (including the 900K+ subs for the World War Two channel plus the subs for the TimeGhost History and new Korean War channel) there's been some discussion and revelation as to what the specific World War Two channel will be doing now that the war maybe wrapping up soon (though they don't give any spoilers).
Apparently one of the things they'll focus on doing is being unique with their 'chronological history' format and that they'll cover more WW2 related topics in a similar format. Along with continuing their special episodes (Viewer Questions Answered, Biography Specials etc) starting this September they'll be doing a special on the Rise of Nazi Germany, starting in 1930 and covering it on a month by month basis with a focus on the domestic political situation and how the various political factions (Centrists, Communists, Nazis, Conservatives etc) reacted and acted and interacted during this time period and viewed each other and the ongoing developments in their country.
And as I posted not too long ago, they'll be covering the Korean War in a similar week by week format
After 314 Weekly Episodes and Six Years of Coverage of the Events of World War Two 79 Years After They Occurred, the World War Two YouTube Channel finished their week by week coverage of the events of the Second World War. The host was actually starting to tear up at the end of it all.
Along with their series on the Korean War which will follow the same week-by-week coverage that started last June, they'll be starting a new series which will apparently be a month-by-month coverage of the Rise of Hitler starting in 1930 and covering it from the POV of contemporary sources in the politically and ideologically polarized environment of Interwar Germany.
They also did an End of WW2 Livestream and were hoping to do it in addition to reaching the milestone of a million subscribers but came up just around ten thousand subscribers short.
The host, Indiana "Indy" Neidell has been hosting so-called real time history format shows like this, including 'The Great War' series as well as this "World War Two" project for a decade now, since 2014 when he covered the event of World War One on the 'The Great War' channel a century after the fact.
