I was in the army and really wished I'd gone in the air force. The army does have some smart people and some high tech MOSs, but there were also a lot of army that were dumb as rocks and always doing dumb shit. The Marines were a little better than the Army, but so many were so brainwashed with their 13 week boot camp that they thought that made them the end all be all. Funny thing is the POG Marines were the worst about it. Navy was alright, I was in back in the late 80's and early 90's so I'm sure things have changed since the combat experience but I wasn't really impressed by the SEALS, I expected more. At that time I'd have put them on par with MEU Marines, expected more but I'm sure it was a matter of hype over reality. As far as the air force, they seemed more professional and for the most part didn't engage in the dick measuring contests, like this thread.
My favorite story about inter-service (which I think I've already told here) was once I was doing forward observing for artillery at Ft Bragg. It was our army team and a team of Marine forward observers. We had a table, chairs, cots, a GP small tent with a pot belly stove...... basically as much comfort as we could carry in the Humvee. The Marines were laid out on a blanket and had their personal tents and bed rolls..... basically only shit they could carry. They would constantly be making comments about our "luxury" and what pussies we were. We were both calling in artillery strikes and we were both taking turns using an old tank as our target, we were both getting close enough hits that would have killed the tank but nothing directly hit the tank. At one point a SUV Bronco type truck pulls up. Two air force guys jump out, grab a blanket, a radio and a "gun" that looked like something out of Aliens. The Marines and us get told to hold fire. The air force guys lay down their blanket, the one guy points the "gun" at the tank and the other guy gets on the radio giving grid coordinates, wind and directions "come in west to east" or something like that, this was in the infancy of GPS. Next thing you know this F 16 roaring in (I don't know if it dropped a bomb or a missle it happened so fast) the next thing I see the turret of the tank flies about 20 or 30 feet in the air. The air force guys pick up their shit and start loading it back into the SUV. The Marines make some comment "chair force, enjoy sleeping in your nice beds" or something to that effect. The air force guys just smile and look at both of us and say "you guys make sure you have a REAL good night tonight" with this "I know something you don't" look.
Just after dark it starts just pouring on us. We dug a trench around the perimeter of our GP small and set a small berm at the bottom flaps (as we'd always been taught to do) so it rained like hell and there were a couple leaks but for the most part we were doing good. We had shelter and a little stove to keep us warm. Someone looked out at the Marines and their tents and gear were all over the place and they were struggling to get their stuff and just drenched. Our NCO yelled over "do you guys want to hunker down in our tent?" the Marines replied "we don't mingle with dogs, we're fine". We were laughing at them and someone made the comment "yeah, they sure showed the air force guys in their nice comfy beds".
