Military units are capable of enforcing martial law.
Military ground and heli units can occupy empty cities – see unit_can_take_over(punit). Some military units, like the Galleon, have no attack strength.

Is this square controlled by the pplayer?
Here "is_my_zoc" means essentially a square which is not adjacent to an enemy unit (that has a ZOC) on a terrain that has zoc rules.
Since this function is also used in the client, it has to deal with some client-specific features, like FoW and the fact that the client cannot see units inside enemy cities.
