Comment: The draft's creator seems to have been away from Wikipedia for some time, so I'm removing the "Review in Progress" box and releasing this back into the pool. NewYorkActuary (talk) 23:20, 1 December 2017 (UTC)
- Comment: I see that you implemented the multiple-use feature for footnotes, but there was a more efficient way to do it that doesn't require re-typing the url. I've re-done them, and you can see how it was done by looking at this diff here.
I also formatted the first reference using the {{cite web}} template. This template makes it easy to provide the reader with the essential bibliographic detail that is called for under WP:CITE. I trust you can use the first as an example for doing the other two.
You also need to provide a brief introductory paragraph that gives a non-detailed overview of the article. Just two or three sentences should be enough.
Ignore the sentence in the "Under Review" box that asks you not to edit the draft. That box is there just to let other reviewers know that I'm handling it. Drop me a note on my Talk page when you're done with the reference formatting and the introduction and I'll be happy to accept this for publication.

The M37 105mm Howitzer Motor Carriage is a 105mm howitzer self propelled gun developed by the United States. It saw combat in the Korean War and remained part of the U.S. military until being replaced in the late 1950s. Approximately 300 were built.
Development and production history
The M37 105mm Howitzer Motor Carriage (named the T76 105mm HMC during development starting in 8 July 1943[1]) was developed off of an extended base of the M24 Chaffee by the US, intended to be the successor to the M7 Priest. It used the same 105mm Howitzer M4 as the ones mounted on M4 Sherman medium tank. The M37 HMC was an open topped vehicle using torsion bar suspension with tracks 16in (41cm) wide. Though the gun performance was similar to that of the M7 Priest, the use of a lighter chassis of the M24 Chaffee made the self-propelled gun easier to handle.[2]
Service history
Standardized for production in January 1945 with all units being built by the Cadillac Division of General Motors, the M37 was built too late to see action in World War II. However, it would see action by the US as an artillery piece during the Korean War.[1] Out of the 448 units ordered, 316 M37 HMCs would be built. The M37's thin armor (0.5in or 1.3cm) could provide protection from small arms fire and artillery splash, but nothing greater. Its "pulpit" machine gun, like that of the M7 Priest, would be used for anti-aircraft purposes, and its 105mm Howitzer M4 would be able to turn a total of 51.7 degrees.[2] Though its basis, the M24 Chaffee, was fast, M37 was much more sluggish due to the amount of ammunition it carried (126 rounds), recoil system, and cannon of the 105mm howitzer M4.[3]
After the war, some units would see service in foreign countries, such as in the Spanish Army.[3] Both the M37 as well as the M7 would be replaced in the late 1950s by the M52 HMC, a self-propelled gun built on the M41 light tank.[4]
