Should Army and Marines (or components of) consolidate?

Oh Hell No. No disrespect, however I knew many Soldiers in the Army that would not have been able to handle Marine Corps Boot Camp, or the Marines in general as a career. We who are Marines ( YES, a Marine for life ) are proud of earning that title. I feel one needs not just the physical tools to be a Marine, but the HEART to be a Marine, and while many soldiers may be very good, they are NOT Marines. Semper Fi to my fellow Marines, you EARNED the title. And to those in the other branches, be proud and do your very best as the Country depends on you...but your not a Marine.

Let’s put the day and night together.

Quick answer no, each serves there own purpose

Leave thing alone we all have a place in the defence of our country

I don’t see a benefit in the Army absorbing the Marines.

When it comes to the basic training of the Army and the boot camp of the Marines there are significant differences in toughness training. The Army has removed so much of the hardcore physical training as well as the psychological toughness training that they would have to play catch up. I served in the army and am proud of the service, however, I have 2 sons in the Marines and 1 in the Army. The differences are greater than people think. If you combine forces of any of the 2 branches then the Army and Airforce would be the most likely branches since the Army started the Airforce.

I am commenting from a position of insufficient information (ignorance) and, even worse, what might be half-truths. Consolidation may have good economic or budgetary outcomes,but I am not sure about even that!
Notwithstanding tradition, pride, etc., I think - from the point of view of an outsider - that differences in tactical doctrine (and related support) have to be considered. My understanding is that a few years ago the Army wanted to absorb Air Force A-10 units, supposedly because they flew in a CAS role and developing tactical doctrine (the role of infantry/armor, attack helicopters, and A-10 type aircraft) would be more efficient "intra-service" rather than "inter-service". One problem I can visualize with this is there is a very human frailty to look with suspicion on something (equipment, training, tactics, doctrine) that is "not invented here". (NIH! CAN'T work!) I am somewhat prejudiced, being indoctrinated into the Marine Corps Green cult. Each branch of the armed forces have something unique to contribute and some of that contribution is the result of a combination of cooperation and competition.
If I am in error in my recollections (notably about the A-10 "rivalry") I'd welcome being corrected.

I included the Marine Air Force with the Navy Air Force.

Consolidate? Currently we have an Army Air Force, Navy Air Force, Coast Guard Air Force, National Guard Air Force, and Air Force Air Force. Last time I checked they all have one thing in common. Start with them.

No, who can think like that in the first place.
Marines had fought in every war separately as a small Element, storm beach & Earned their respect with all branches regardless how we feel about them.
We must never allow to join as one due to what they do.
My branch is disgusting themself as a multi unit.
We have Paratrooper, Diverse demolition transportation so many that we are a bigger army for that reason.

We can do with our join forces.
