In the ME place any ship (only tested with blue).
Place static object on ship and link to ship.
Load mission and the static unit will show up on the map, one on the ship and the duplicate at another location (On Persian Gulf for example the unit will show at Khasab right next to the runway).
It would not be that big of a deal since the actual unit cannot be seen, just shows on the map, BUT enemy units will try to engage them. It happens on Caucus map as well (unit shows on the big empty island), have not tested Normandy. Seems only static "linked" units do this.
Edit: Just tested the 'Instant Action' F/A-18 Carrier Cold and Dark, same issue. Maybe this should be under 'General'
