Yes it does.

but from my experience this is not how it works...
I believe its more of a pairing algo than a real fighting algo..
so for me it seems as if all the long range units of the attacker are paired to the melee defenders first.. than the single unit attack power is compared vs. the defend power and the defending units killed... maybe using some probability /chance algo..
the defending units are paired with the attackers melee units and same procedure... if there are more attackers than melee defenders, the defenders range units also get attacked.. and vice versa..
the next turn every melee unit still standing is paired to the opposing units still standing..
and every unit.. how large their attack value is.. only has one shot.. so bazooka guy shooting rowdy.. one shot.. one hit.. one kill.. that's it...

doesn't make too much sense so.. so I believe they will change it...
