Glad you like the sheet; I tried to keep it looking nice as well as having all the info on it - makes it easier to see what's there :)

Definitely like the idea of - to borrow term from an old TTRPG - the 'masquerade' being in effect so that Joe Public isn't really aware of anything. Although, I do like the idea as with all of these things that there's probably a few conspiracy nutjobs out there who are closer to the truth than they realise... and just as equally, there's an office somewhere in a big intelligence agency that deliberately posts messages to fuel the fire and at the same time send them off on random tangents. 

With you on the ATGMs, the mini-missiles aren't a million miles from reality anyway; smart munitions are getting smaller and more precise seemingly every day, especially with things like the [url=https://en.wikipedia.org/wiki/XM25_CDTE]XM25[/url] being a reality. With the Shoulder-launched Hellfires, Stinger and APKWS I was basically envisaging them as a tube with the missile/rockets in that's ejected or discarded once they're used. 
With the recoilless, I'm basically thinking of a carousel-fed Carl Gustav, with a few different types of munitions ready to go. Again, enough of them can kill armour, but mostly they're for breaching, or taking out large or hardened targets and positions, or groups of hostiles. 

Will take a read over of the post and get something up later today!
