If you join three meks to a unit of X boyz and a warboss, the warboss is also allowed to leave that unit, even if everything but the three meks has been shot to dead. It's pretty much the same as the big mek leaving his three meks. Three meks can form a unit which none of them can leave.
There also is a downside to these shenanigans, since you have to deploy your big mek with the three meks, since there is no rule that allows an
IC to leave a unit before the game starts.
pretty much this.
if joining a unit would be a "two way thing" an
IC could never leave a unit he joins, since 'a normal' unit cant leave/join another unit. this would apply to all armies/
IC's
