Strummingbird, that's more of a comment on how absolutely shit most of the US commanders are.
Honestly I would disagree with that. Assault engineers do boatloads of damage despite being fragile (I recall a post stating that they do more damage than assault grens). They also have flamers, which are very useful since the US faction gets none normally. Add to that the demo charges and repair and you get some very nice utility. Wolverines are getting a buff next patch, and you can go T2-T3 and call in armor with the 105mm which has solid armor/health for a medium tank.
Rifleman doctrine gives your rifles flamers, which kinda defeats the point of ass engis except as a very early call in. Phosphorus drop used to be insanely good, not sure how it does now. Veteran rifles take longer to build but are definitely very strong , and the crown jewel- the Easy Eight- is a better allrounder than any other medium tank (on par or better than the T3485).
Just to compare, it has 215 armor and 175/165/155 penetration, more than any other medium tank (bar vet 2 P4s, armor-wise). Good speed , good reload, lots of utility with smoke, has vehicle crews to self-repair, for 10 more fuel than a Panzer IV.
