No offense, but that is a dumb question and begits dumb arguments.
Everyone who ever served on active duty usually has some pride to a lot of pride in the unit he was assigned to, as well as the service he chose (or in some cases, chose him...) All of them have their merits and demerits, but there is a common pride in having served in the Armed Forces Period that many civilians do not understand nor will they ever find a similar relationship unless they are police, firemen, or others who have to work as a tight-knit team under highly stressful conditions.
This isn't meant as a dodge or a PC sop; I served with the Army Security Agency with great pride until it was subsumed by the Intelligence and Security Command (INSCOM) which I do not feel as strongly about due to its less mission-oriented attitude. (If you were in ASA, you better have your sh*t together and know your MOS forwards and backwards; in INSCOM, running, weight control, and PC training took a higher level of priority...) I'll stack the ASA units I served in against any group of USAFSS, NAVSECGRP, or "CT Marines" going.
But I have a lot of respect for the "competition" because they were there and many others weren't.
