What do you get when you lure a SAG (Surface Action Group) out away from the coast and then let them run back into the bow of a Type 209 submarine?
Unlike my colleagues on the Army, there is no advantage to reserve forces in a naval engagement. Warships perform best when they can concentrate their fires and overwhelm any maneuver, armour or defenses of their opponent.
Or take them by surprise from below the sea.
I would not want to contend with any of the Chilean submarine forces. They are sharp.
