The polished brass navy has had a boner for the SEALS for a while. My friend, who was a plankowner in the original SEAL Team 6 said they didn't have to be in uniform, stand watch, had their own part of the ship, IOW weren't "regular Navy", and I have little doubt that caused no small amount of irritation among some who did not appreciate their skills or mission. Not being part of the normal command structure has been a thorn in the sides of some officers who will likely never deal with an enemy at arm's length or closer.
@Smokin Joe We had the same problem in SF. Some local commander would see a recon team at a fire base in his area,and come up with the bright idea that he was going to commander them to serve his unit. They didn't like it when somebody with sterile fatigues that he KNEW was enlisted swine would start out by saying "Nope,not gonna do it. We already have missions to run,and they come first.",and it would usually devolve to "go piss up a rope." This was particularly true of USMC Colonels.
Hell,on occasion we have had conventional army officers try to confiscate the CAR-15's or AK's/RPD's from our yards to keep as their own personal weapons. They were outraged that "some primitive VN has a CAR-15 and I don't!, WAHHHHH!". I saw a damn fool Captain come close to getting shot at the Kontum airfield one day over that crap. To this very day I doubt he understands how close he came to getting killed when he tried to snatch it out of the hands of a Yard recon team interperter/team leader. He did seem to understand reason when it was presented to him as a 45 held against his temple,though. A calm,soothing voice and a 45 will make a lot of people reasonable.
Keep in mind we were all wearing sterile uniforms,and the yard point man was dressed as a NVA,pith helmet,AK-47,and all. He had no idea who we were,or even who to complain to about us.
The "wear red and march in a straight line" military ALWAYS hates unconventional units and soldiers because the regular military forces are conventional by nature. What really make their bells ring is when they would get mad and demand our ID's so they could write us up,and we would truthfully tell them we didn't have ID cards. There was just no way they could wrap their heads around that.
