I left those two because it seems to be more of a spinoff universe that's not connected to the one inhabited by Wildlands1 since the pandemic of The Division take place between late 2015 to summer of 2016 with devastating effects (clearly a Class 0 or possibly Class 1) that doesn't seem to be reflected in the "main" timeline.
But yes, the Last Man Battalion and Black Tusk definitely count as well. It's probably easier to write up a fictional PMC as the enemy so you don't offend anyone.
1. Crossed over with Splinter Cell, Rainbow Six, and indirectly H.A.W.X. by way of Advanced Warfighter 2.
