Freyhay, this should give you a head start with multiple grouped trigger objective.

All 3 ships must be destroyed before the objective is complete.
Use it for just about anything. Your Triggers are called Ship1, ship2 etc.

    int TotalRedShipsDestroyed = 0;
	const string Objective_Ships = "  English Supply Tankers 3 of 3,";	//BlueObjective  RedShips Destroyed

	bool ship1 = false; 	//English Supply Tanker 1 of 3	ship1
    bool ship2 = false; 	//English Supply Tanker 2 of 3	ship2	
    bool ship3 = false; 	//English Supply Tanker 3 of 3	ship3



  public override void OnTrigger(int missionNumber, string shortName, bool active)
    {
        base.OnTrigger(missionNumber, shortName, active);

            if ("ship1".Equals(shortName) && active)
                {
                    TotalRedShipsDestroyed++;
                    GamePlay.gpLogServer(null, "British Ship " + TotalRedShipsDestroyed.ToString() + " of 10 destroyed!!!", new object[] { });
                    ship1 = true;
                }

                if ("ship2".Equals(shortName) && active)
                {
                    TotalRedShipsDestroyed++;
                    GamePlay.gpLogServer(null, "British Ship " + TotalRedShipsDestroyed.ToString() + " of 10 destroyed!!!", new object[] { });
                    ship2 = true;
                }

                if ("ship3".Equals(shortName) && active)
                {
                    TotalRedShipsDestroyed++;
                    GamePlay.gpLogServer(null, "British Ship " + TotalRedShipsDestroyed.ToString() + " of 10 destroyed!!!", new object[] { });
                    ship3 = true;
                }
				
				
				 if (ship1 && ship2 && ship3)
                {
                    GamePlay.gpHUDLogCenter("English Supply ships headding North have been destroyed!!!");
                    GamePlay.gpGetTrigger(shortName).Enable = false;
                    Timeout(10, () =>
                    {
                        GamePlay.gpLogServer(null, "Blue Objective  Completed!!!", new object[] { });
                        GamePlay.gpHUDLogCenter("Blue Objective  Completed!!!");
						Objective_Total_Blue += (Objective_Ships);
                    });
                }
