What suggestions do you have for renaming DoD installations honoring Confederate officers?

Leave them as they are .

None. I've never related an installation's name with its namesake's service during the Civil War.

They are not honoring confederate officers they are honoring solders do not make solders political
Renaming post is just political When I say I went Jump school at Ft Binning No one will know
Where that Post is The Army is not , Military is not Political THEY ARE BOTHERS and SISTERS
IN A FAMILY. WE AS A FAMILY DO NOT NEED TO BE ON THE WRONG SIDE OR SPLIT
I WAS ALWAYS TOLD THAT I WAS NOT BLACK OR WHITE I WAS GREEN

In my opinion, if you are easily offended by a name that has been around fora very long time, you have bigger issues that you need to be dealing with. No one was offended by these names until someone said to be offended. Before then, it was ok, lets make our rotations at NTC, JRTC or where ever else they may be going to train or get stationed. The problem we have today is, no matter what, someone is going to be "Offended" by something, doesn't matter what it is. If you paint something red, people will complain because it's not blue. Get the F**K over it, be a Soldier, Sailor, Airman, Marine, Coastie or Space Force and quit thinking everything is offensive. There are lots of things that I don't like, I don't complain about it, I just move on about my business. Unless it directly affects me (physically), who gives a shit what name is on a sign or billboard. I honestly don't care if anyone agrees with me or not, that is what makes America so great, we are all entitled to our own opinions.

Leave it alone.

Fort Bragg - Fort NUTS - the most famous word said by a member of the 101st Airborne.
Fort Rucker - Fort Frederick E. Humphreys - the first US Army Aviator
Fort Benning - Fort George C. Marshall, assistant Commandant and champion of the Benning Revolution. He did other things you might have heard of, later.
Fort Gordon - Fort Albert James Meyer, first and only Signal Corps Officer for three years
Fort Hood - Fort Robert L. Howze, Medal of Honor recipient and first commander of the "First Team"
Fort Polk - Fort Mark Wayne Clark - second in command of the Louisiana Maneuvers which founded Fort Polk
Fort A. P. Hill - Fort William Crozier - 11th Chief of Ordnance, oversaw the introduction of the M1911 pistol, M1903 rifle, M1918 BAR, and M1917 machine gun.
Fort Belvoir - Fort Andrew A. Humphreys - the original name of the facility (Union Civil War general and Chief Engineer)
Fort Lee - Fort Thomas Mifflin - first Quartermaster General, member of Continental Congress, signer of Constitution
Fort Pickett - Fort Lafayette - the name National Guard arises from the Frenchman who fought in the Revolutionary War when he toured the US after serving as commander of the Garde National de Paris during the French Revolution.

Well, if we're "mandated" by the mindless and milquetoast left to change the names of all of the Confederate-named bases, here's my suggestion. Put the ones to be renamed in alphabetical order, then name them " Fort Too Stupid To Understand History #1", then just follow in numerical order.

Fort Hood - Fort Quanah Parker

Rename Fort Bragg to Fort Aaron Bank, the founder of Special Forces and the first commander of the 10th Special Forces Group.

FORT ARAGORN, FORT FARAMIR, FORT BOROMIR, FORT DUNADAIN, FORT HARALBRAD

If you're going to rename the Headquarters of the 75th - then it has to be the name of a Ranger. But since MOST real people are assholes, I went to the next obvious place; Lord of the Rings. These are the names of all of the Rangers in the Lord of the Rings that I can remember, and I'm sure that there are plenty more. The Dunadain were actually the people, but their biggest presence were the Rangers of the North.
But I truly think the Army should give Aragorn a posthumous MOH.

for the other bases -

FORT SKYWALKER, FORT SOLO, FORT ACHILIES, FORT PROMETHEUS
