Hi!
I have used the Skeleton Bones (Archer) a few times to summon archers. Occasionally they seem to do well, but... most of the time, they just unequip their bow and charge in to do melee. Not sure if it's tied to anything specific or if I'm a dofus, but I didn't even give it any commands this time, it unequipped it and ran into the fray. Thought it might be a bug.
It's a long standing bug. If you fiddle a little sometimes you can get them to equipt melee weapons when it happens.
