Why does the Army not have as much pride as the Marines?

Marines are overcompensating, trying to prove that they aren't part of the Navy....

*Ducks and runs for cover*

One of my brothers was a Marine and the other in the Army. I was an AF medic during the Vietnam Conflict. Other members of my extended family served in the Navy. None served in the Coast Guard. Many Marines I have talked to believe that those in the Army are "wannbe marines and know they are not good enough". As far as the AF they see us as the cub scouts of the military branches. They admit we have better food and facilitates! They do not disparage the Navy.
So the marines are prideful. Yet they are committing suicide at high rates. I have published articles about this dilemma. I highly recommend "Shooting Ghosts" written collaboratively by a marine and photo journalist. So, there is a heavy price they pay to remain "Semper Fi!

Because we aren't brainwashed into thinking we're the greatest thing this side of indoor plumbing?

With all due respect... I believe this question is disrespectful, prejudice, and uninformed. The premise of the question perpetuates the notion that one area of our service can be better than the others; we all know that's bull. The Marines are a combat arms monoculture type organization where it's realitively easy to get that prejudiced response from their members, without them realizing they have to rely on many others for "their survival". Think about that for awhile. To some degree the answer some gave here: that Marines are a cult, is true. I respectively submit this attitude isn't good for the Country. PS: I have several friends who are Marines, one is deceased, and is my best friend.

Like the Navy, the Marines have a focus on tradition. The Army was never like that for me. That tradition elicits a lot of pride.

I think it has to do with the sizes of the services. In my experience elements of the army combat arms units of similar size ie Airborne units and Rangers, Armor units and air cav. Have equal levels of pride! Special ops units have even more pride than the Marines. I think the pride is based in past present and future combat successes. The army is huge as a whole and has more support units than combat arms. I know all the elements make the whole work and are needed and still the pride of service for most comes from the feeling of being a warrior not support.

Every unit I was in had a great degree of esprit de corps (no pun intended), they were all infantry units which were completely different from any other branch in the Army. Things I saw in POG units would never be tolerated in a line unit. When I was a support platoon leader in an infantry battalion I had a bunch of 88 series truck drivers. They had never run 5 miles before but we worked up to it. Everyone bitched their share but don't dis the unit in front of them if you weren't one of them.

I served in the US Army for over 20 years and had the opportunity to work with all of the services in a joint assignment. The Marines are the smallest of our services and perhaps their smaller size fosters an attitude of elitism that is seen in their fierce loyalty to the Corps. By contrast, I think the loyalty toward the Army as a service is diluted due to its sheer size. The Army has great morale at the large unit level (i.e., 82nd Airborne, 101st Airborne, "Big Red 1", The Cav, "Rock of the Marne (3d ID), 75th Ranger Regiment, Special Forces, etc.) High morale and close unit identification among soldiers is very evident in within battalion and brigade-sized units. Where you see poor morale, you generally find poor leadership. The size and diversity of the Army's missions and focus make it hard to foster intense loyalty to the Army as a whole. Consider the differences between the Army Corps of Engineers, Army Materiel Command and 1st Special Forces Group. All are critical to the Army's overall mission and purpose; all have vastly different mission focus.

We're humble.

I can't speak for Army because I've never been in the Army. So, if there is more pride in USMC I couldn't verify it. I have been out of the USMC almost 20 years, so I can't speak for pride now. I believe it's as high as it has ever been though. It could be that Army pride is higher than you realize. The Army units I've been around seemed to be proud and professional. One factor could be size of Army vs. USMC. The greater the numbers the larger cross-section to sample. It may be related to basic training also. A slice of USMC boot camp covers the history and achievements. My guess would be that boot camp itself is where it starts. It's a rite of passage and that is reinforced and upheld at every unit thereafter. The esprit de corps is a central theme of all Marines once they get assigned to a unit and stays with them for as long as they serve. I'm sure it exists in the Army as well, but due to the larger numbers it is less apparent in certain units.

Edit: Added 12/23/17 Same idea and didn't realize I had already responded.

I haven't been around enough Army to say, although the ones I have served with were pretty motivated and squared away. It depends on who you ask though. One reason might be larger service = more people = greater odds of finding disgruntled and less than motivated soldiers. If you go to towns around large USMC bases you will find great numbers of "ex" Marines that aren't overly fond of the Corps, as opposed to former Marines and those that live by the "once a Marine, always a Marine" creed. The distinction between "ex" and former being the same as an "ex" wife from a bitter divorce as opposed to a former spouse that is still on good terms with the other spouse, but divorced because they just had irreconcilable differences.
