Power
You have the power of the sea. Poseidon himself is impressed with your strength and swimming ability.
You have the power to save lives.
You also have the power to police the waterways, pulling drug runners off ships and arresting them to protect our ports.
When ice blocks waterways, when hurricanes and tornadoes rip houses off their foundations, and when seas swell to tsunami-like proportions, you have the power to jump right in there and save people.
Of course, you'll have little power aside from that derived from the self and the team. When your commanding officer says "jump," you say "how high?" (Or, more appropriately, "out of what?") You'll have a lot of physical power and situational prowess, but you'll live your life based on the unquestioned obeying of orders, which is sort of the textbook definition of non-power.
