And I'm still using the term "puma" is because they are the most famous and successful use of agility, sight, range speed, dodging, and smoke to survive. I suppose we could use DRASSS.
And there many differences between Puma and M36 you are proposing, both in stat and in optimum usage.
Puma has TS of 18 (smaller than average) M36 of 24 (large than average)
Puma has a disabling ability better suited for allowing to close in, M36 has penetrating ability better suited for sniping from far.
Puma has very low far accuracy/penetration that improves greatly in sorter ranges, M36 has a rather linear curve and it get most out of firing out side the range of its opponents.
