Checking out the upgrade cards that come with the OP blind boosters and was curious about how Improved Overrun and Troops that lose soldiers work. The last line of Improved Overrun's rules text says:
Must have a Primary Weapon Value of 3 or higher to equip.
So if I have this equipped on a full Sun Elf Archer Troop, does the upgrade "fall off" when I lose soldiers and my weapon value drops blow 3? (In this case when I get down to three or fewer soldiers remaining.)
My guess would be that if the unit size is built large enough to legally equip the upgrade to the unit prior to the game, then regardless of losses suffered by the unit during the game it'll be able to use the upgrade. To me "equipping" is different than in-game conditions requiring a specific unit size to use an upgrade.
