This is easily boosted with a partner. Simply start an Island Capture session and have your opponent build a transport and send it toward the middle of the map. You build a destroyer or PT boat, activate the Tactical Map and then select your ship and direct it toward the middle of the map. Do not press ESC at any time to ensure you stay in the Tactical Map view. As soon as the enemy transport is within visual range, tell your ship to attack it. As soon as one shot hits, your partner can surrender and the achievement will unlock.
