Torsion Bar Suspension and 76mm gun the same as Sherman Easy 8 gives good accuracy on the move and the same weapon as Easy 8 and T34/85.
A whopping 92km/h top-speed compared to 46 km/h of late war Panthers, 48 km/h of M36 Jackson and 51 km/h of M10 Wolverines means this unit could traverse 3v3 and 4v4 battlefields to deal with specific threats.
The M18's Wright R-975 engine is mounted on steel rollers that allow maintenance crews to disconnect it easily from the transmission. This Td is well known for its ease of maintenance. Maybe it can repair faster or is less prone to engine criticals.
Cloaking was on the M18 in vCOH and it could easily be added here.
The M18 also had an M2 Browning .30 cal machine gun which could be upgraded and have some Anti-Infantry capabilities.
Maybe balance this units great strengths by making the crew vulnerable to freezing during blizzards as they were prone to be due to the open-topped nature of their vehicle.
TLDR:: Bring back the M18 Hellcat in a commander that is specifically suited to team games and anti armor (U.S. repair stations please!) It would fit nicely as the U.S. analogue/counter to the Axis Panther and is beloved my many. Me at least.
