MNOC grads are held accountable for maintaining their skill. It may have slid a bit in the past because the high turnover rates during the war or whatever, I wasn't there yet, but from what I've seen is each team has 2 junior CSOs or 1 junior and an AEL who are responsible for team comm(MNOC grads). And this is true for my battalion at least, I can't speak on behalf of the others. I'm not disregarding a SOC-C is replaceable or irrelevant but it's not a point of failure at the team level. It is a company level asset, but is mission enhancing to a team to take a good bit of the burden off the shoulders of an MNOC guys to focus on other responsibilities. As far as the lack of knowledge on basic comms up to a 148 that's a negative blanket statement and that's on the team if that holds any truth, that sure isn't the case for everyone.
Any who, just my 2 cents. The tattoo, I wouldn't do it man, that's Recon's piece of history, that's like me getting a jack, while yes I may possess those same skills as my Reconnaissance brethren, I didn't goto BRC. Do something in regards to history your organization has now, or be prepared to always answer to someone who questions you about the origins of your jack.
