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

The Army is huge, it is far larger than the USMC in sheer population. We have more room for internal divides to take root. People get bored so that's what ends up happening.

There are divides within the USMC (deployed/fleet Marines vs. stay-at-home Marines, etc) but because it is a smaller service these divides don't take root in the same way, I'd wager.

I think it depends on how you talk to, I was very proud of my serving , even though it was the Army Guard, 85% or better of the people I served with were proud of the military service.

I spent time in both The Marine Corps and the Army. It all comes down to the Army's understanding of dicipline and the soldiers understanding of self dicipline. All I can say is I am very proud and glad to have earned the title "Marine" before I was Army.

Marines just have better PR, Army has just as much, if not more, pride.

Sgt Kennedy is correct; pride in the Marine Corps is for the Corps itself - at that level. You may be an aviator or a grunt, but you are a Marine first. In the Army, and this was stated to me by friends who served in the Army, pride is derived at the Regimental level or the Branch level.
There are plenty of reasons for this, but if I had to guess it is because the Army has different "realities" and entry paths to it that the Marine Corps does not. The Marine Corps only has 2 paths, in two locations to becoming a Marine. All officers go through OCS at Quantico, VA or you go through one of only 2 recruit depots. Once complete, all officers go to The Basic School - literally all officers, without exception, commissioned and Warrant Officers.
The Army is sufficiently large enough that two officers serving side by side may have entered through completely different paths and didn't meet up until they are in their specific unit.
Finally, there is no Big Marine Corps and Special Operations, as there is Big Army and Special Ops - there is just the Marine Corps. So, you can serve in the Big Army and have a completely different reality with regard to gear and funding and support than your friends in Special Operations. All of that adds up to pride in the unit or branch vice the service level.

Young men join the Marine corps to prove something to themselves to their families as a rebellion to being told they're not good enough, not tough enough. This is where we all started and once marines we were steeped in the the stories of Dan Daly, Chesty Puller, John Basilone, As marines we were more afraid of not measuring up to the marines who stormed Tarawa or took Tripoli or raised the flag on Iwo Jima. As Marines we have an identity that is real and unmistakable, we are the Few and the Proud. We fight for each other, lose is word we don't know, the best way to get a Marine to do something is to tell him that he can't. I hope this sheds a little light Semper Fi

I worked with all Branches & served with Prior Service Branches as well. At the end of the day it didn't matter. We all took pride in our Service but all Marines reminded me the most of 82nd & the Pride we felt. When you train to be the best, you take pride in it. Paris Island teaches that from day one. Army leaves it up to whatever Division you end up in. Some are better at it than others.

The Army and Marines are totally different organizations, its hard to equate the pride in one with the other. A universal feeling of pride in the Army is very hard to achieve. The pride and history is locked away in divisions and to a lesser extent the MOS's. Im more apt to tell people I was in the 1st Armored Division (Old Ironsides) then just saying I was in the Army. Your corp history may be more prevalent but in the Army the story and history of the Division is focused on. Your universal pride is hard to achieve with something so vast and varied as the modern Army.

This is a tricky question, but a valid one. I spent 6 years on the Marines, and then switched to the Army and stayed until retirement. Having served in both branches, I know that it is true that the Marines instill a great deal of pride in their recruits during Boot Camp. This is done by making Marines learn about the battle history of the Marines.
The Army also has a great battle history, however the Army does not seem to emphasize it to soldiers. Knowing the linieage of your unit creates pride. Some units in the Army have more pride than others, for example the 82nd Airborne Div. or the 101st. The soldiers in those divisions know that they are part of a long line of great American soldiers.
The Marines is small enough (with only 3 active duty divisions) that all Marines feel like they are part of the same team.
The Army is much larger and suffers from alienation amongst its own people. For example, if you are a soldier and see another soldier wearing a division patch from a unit that you are not part of or never been in there is an unspoken feeling that this soldier is different than you somehow. The nature and culture in one Army division is often very different from other divisions. In the Marines each division is basically the same, just located in different geographical locations.
It boils down to this: in the Army am S1 clerk or a supply officers daily duties are not that much different from an equivalent job in the civilian world. The Marine clerk or supply officer have been taught from day 1 that they are primarily Infantry riflemen, and can be called upon to serve as infantrymen when the situation requires it.

Ask any infantryman and he'll tell you he has pride in the infantry. But we will all piss and moan over the bullshit of the big green weenie that same day.
