[Any "Fight to the Last Man" mods now that "Fight Aggressively" disables itself?]

Any alternative mods that can replace "Fight Aggressively!" as a mod that'll get armies to fight to the last man since it disables itself since the last update and it's no longer offered as a mod? I don't like retreating troops...

 

 

[Grendel and Beowulf rifles]

Is there a mod that has the 6.5mm Grendel AR-15 variant rifle and/or the .50 caliber Beowulf AR-15 variant rifle?
