Battlefront is featuring their M36B1 Jackson tank for Flames of War.
From the article:
While building more 90mm tank destroyers, a shortage of M10 hulls has led our factories to substitute them with the M4A3 chassis instead. This has resulted in a tough hybrid, known as the M36B1. It’s fast, better protected, and armed with a hull-mounted .30 cal machine-gun, making it an excellent support weapon.
