M-48A3

I will fix the tracks and the vision blocks. Thanks for the comments

It's actually the 11th Armored Cavalry Regiment also know as The Black Horse Regiment.

It's a good build, I'd add some bolt detail to the spare road wheels so it looks like something is holding it to the grunt rail besides magic!

Also the vision blocks in the cupola riser and on the cupola itself are still painted over; I'd touch up those glass areas with some gloss black or dark blue.

There's a lot more good than bad in your effort. The tracks are on backward; a little fine tuning and there'd be nothing to be upset about.
