Should Army and Marines (or components of) consolidate?

No. Marines (Navy) and Army have separate missions.

HELL NO !!! If the Army wants to join the Corps, they are welcome to do so. Marine Corps Recruit Training, (if you can) then advanced training, then whatever. There is a reason why NO MARINE will EVER have to go through any other boot camp in their lives. You do NOT get to become a Marine any other way. As for the Marines wanting to become the Army, why the hell would we? The Army needs heroes to admire too. Of course this had to be asked by a Squid. Thanks buddy. Stirring the soup again. The safest place in Korea was right behind a platoon of Marines. Lord, how they could fight!
MGen. Frank E. Lowe, USA; Korea, 26 January 1952 : Why in hell can't the Army do it if the Marines can. They are the same kind of men; why can't they be like Marines.
Gen. John J. "Black Jack" Pershing, USA; 12 February 1918 : We have two companies of Marines running rampant all over the northern half of this island, and three Army regiments pinned down in the southwestern corner, doing nothing. What the hell is going on?

I was Air Force, I can see where consolidating for a mission would be worth it, but for the most part we all have different missions and different ways of operating, even within branches. I don't think consolidating branches would have any more benefits than just finding a better way to cut beurocratic bs.

No. Each branch of service has it's own particular mission and capabilities. I am a dual service Veteran (USMC 1995-2005, US Army 2009-2018). Marines are a completely different breed. During my time in the Army, I never encountered training for non-infantry Soldiers that equaled that of non-infantry Marines. (I'm not even going to debate Army Infantry vs. Marine Infantry, MARSOC vs SOF etc.) Everything from PFT / CFT to Weapons Qual was completely different. A vast majority of soldiers could not successfully engage a target with iron sites as do Marines at distances greater than 300 meters. Marines focus heavily on weapons training while the Army does not. Weapons Qual in the Army is done in roughly 2 days. 1 day for a PMI and the 2nd for zero and qualification. The Corps' Weapons Qualification is 5 to 6 days. 1 day for PMI and "snapping in," 2 days of practice, 1 day pre-qual and 1 day qualification. The extra day was for reflexive fire, multiple target drills, MOPP gear qual and a night fire. This is only ONE example of how both branches differ. The advantage to having The Marine Corps under Maritime Law is invaluable as landing Marines on foreign territory does not constitute an act of war. Consolidation would also be a huge financial and logistic debacle. Pride in earning the title of United States Marine alone is reason enough to consider this idea laughable.

No, No, No....

Marines and mythology go hand in hand!

No! I mean no offense to the Marines but being tactical in other areas of technology such the Army is ,requires a pride in more than grunt work ,which ultimately saves lives and win battles...

NO!!!!!! NUFF SAID

NO!!!!!! Nuff said

probably not. too much culture, tradition, and similar but NOT matching missions, role, and many other elements.
HOWEVER, where possible, consolidation of function, support, etc is Quite effective, and cross over training and interaction should ideally results in betterment of both branches. FOR EXAMPLE... many of the Joint Forces Military bases bring many benefits.
