I recently had the chance to do some collaborative filming with Nicolas Moran , and figured it would be a good chance to do a Q&A specifically on issues related to tanks. Nicolas is a Major in the US Army Reserve, who deployed to both Iraq and Afghanistan in Abrams tanks and Bradley APCs, and is a wealth of information of armored vehicles both past and present. I learned a ton speaking with him, and I think many of you will also in today's Q&A (which, I will note, is my longest such one to date!).

The questions provided by Patrons are:

0:01:10 - The M85 machine gun and M231 port-firing weapon
0:05:44 - Which machine gun position is best, coaxial, hull mount, or top mount?
0:18:02 - Is the 25mm gun on the Bradley still viable, and do its TOW missiles need to be replaced?
0:23:28 - Do modern tanks have bird's-eye type camera systems?
0:26:49 - Given the headspace problems on HMMVW M2s, how bad were your secondary weapons in the Abrams and Bradley?
0:30:57 - What happens to spent casings in tanks?
0:33:58 - Given the effectiveness of AT rifles in the 1930s, was the "cult of the machine gun" really a bad thing?
0:37:25 - Thoughts on the Swedish S-Tank?
0:42:00 - Will the current Army competition for a light vehicle lead to anything?
0:45:08 - Differences between the Sherman 75mm and 76mm in AP and HE
0:47:12 - What about a 20mm-30mm auto cannon as secondary tank armament?
0:52:48 - Will man-portable anti-armor weapons remain viable in the future with unmanned vehicles?
0:56:50 - What are tank crew small arms like?

1:14:00 - How significant were optics and fire control systems in WWII tanks?
1:21:48 - Do other countries have the same bureaucratic procurement issues as the US?
