Using the Sherman Crocodile

[Coyotesax]

Ok, played US Rangers for years,
But saw the Sherman Croc model and just have to play it. Cool factor through the roof!

I was wondering how to play this unit both historically,
and tactically.
1. Can you give me a clue as to the types of units it might best support? Can I use Rangers or any other unique infantry units?
2. I realize the benefit of both a 75mm gun, a flamethrower and up to 2 MG’s (buying the .50)
a. How do you mitigate the armour threats? Sure to be some TF Pz IVs or worse lurking about. Not to mention 88’s and pak40’s.
b. It is slow. How do you get the thing in range, or is it just a waste for 2 turns as you run forward? This also gives the enemy some free shots before you ever think of returning fire. Ugh.
c. Is veteran worth it for stabilizers on a slow tank?
d. What would you take in a list to enhance its effectiveness?
e. How would you deploy it tactically to make the best of it? E.g., Do you always keep a squad nearby, etc?
Thanks for helping me work through this.
