I've played quite a lot of Men of War: Assault Squad and vanilla Men of War only to notice the same thing. The game offers a huge amount of various units to use yet there seems to be some units that remain untouched; units that you only see relatively new players using because they don't know any better. What I want to discuss is if any of these units actually have merit however situational that use might be. My list of forgotten units is as follows:

Axis:
PzKpfw I Ausf. B
SdKfz 232
Luchs
Flakpanzer
Jagpanzer IV
Brandenburg
Faljimjagers

Allieds:
101st airborn
Marines
Chaffee
Calliope
Willys AT
Wolverine
Zippo
Jumbo

Both:
Flamethrower
Officer

Many of these units usually serve a redundant purpose with a much more fashionable unit. Another question I would be interested in watching people discuss would be why one unit is so much more popular than the other though they serve similar tasks. My list of redundant units is as follows.

Stuart vs. Chaffee
Hellcat vs. Wolverine
PzKpfw I Ausf. B vs. sdKfz 22
sdKfz 232 vs. sdKfz 222 vs. Luchs vs. Flakpanzer
Hertzer vs. Stug
Panther vs. Tiger

I would just like to add that I LOVE the ability to choose from a whole slew of units, even though I always pick the same ones.
