Sunshine's co-pilot is wearing the rank insignia of a Lieutenant (Junior Grade), but Sunshine is a Chief Warrant Officer, yet he gives her orders, an officer outranks a Warrant officer. The co-pilot is subordinate to the pilot, so if there were on officer on board the chopper she would be the pilot and Sunshine the co-pilot.
Except that there are some circumstances where the pilot (in command of the aircraft) is junior to the officer sitting in the co-pilot position. This is most often seen in training missions, however, can still occur in real-life missions, most often when there is a skill/qualification disparity between the junior and senior officers. In such cases, the senior officer would be considered the mission commander (in charge of the overall mission), while the junior officer would be considered the aircraft commander.

The external scenes of the Greek ships show real Greek navy frigates, but not Hydra class. These are earlier Elli class frigates.
The internal battle scenes on the Greek ships are all wrong. Combat operations would be controlled in the CIC, not on the bridge with a joystick. Crew would be wearing flash gear.
Lucia's ship was badly damaged, enough that they had to abandon. They were well away from her father's ship. Yet, it had to have been close enough for her to make it back without alerting Nathan James.
