Yes, it's the worst USF commander. I tried so many times to make use of its abilities.
The WC51 definitely needs an update on its performance and cost. Even a kubel will wreck it
For a mechanized commander, it could use any of the following:
> call-in riflemen equipped with thompsons
> coordinated ability (like the support commander)
> M5 call-in (this can combine with the thompson-equipped riflemen)
> Rapid decapture w increased vehicle/tank speed
