Don't give up on TD's yet!
The U.S. M10 or Wolverine Brit's version. can be very useful,if used in hilly terrain where they can use thier fast speed to shoot and scoot.
They have the longer ranged guns with a punch, so should also kept far back., they are thin skinned and eventually will catch a hit in a long campaign,so might be better bought as support.
Just my 2 cents
