The Delta motto is essentially 'to serve and protect'. But how does the SLI play a part in this? I always saw the SLI as the lazy self-indulgent one who just liked to play around with mechanics. It's easy to see how the LSE would serve and protect; the best soldiers, admins and CEOs are LSEs; they have social and environmental responsibility, and they are well-organised and effective people. Delta NFs help people with their creativity (IEE) and their values, principles and morals (EII). But how does the SLI help anyone?
