Dagnab it, do these people not understand the meaning of 'Mission critical objective'? We cannot afford to lose the Lighthouse, and with XCOM ERUSIA already stretched thin to cover the other branches, and the continent undergoing a bloody civil war, we cannot spare those pilots without fatally compromising our ability to hold it. We've already given as much support without risking the loss of the Lighthouse, and rendering any attempt at a counterattack immeasurably harder.
