With WW1 Russian troops on the horizon, now might be a great time to come out with WW1 German Cavalry to be their foils.
Cavalry generally had an active role on the Western front during the first and last year of war. On the Eastern Front the deadlock of the trenches never developed and cavalry played a major role the entire war.
Perhaps the kit could have seperate legs and two sets of torsos.
Double breasted "Uhlan" torsos for the early war. (Young Richthofen in the cavalry anyone?):
And single breasted tunics for the rest of the war:
A mix of pickelhaube, stahlhelm, and stahlhelm with gas masks would be welcome.
Reasons to do this kit:
1. Supports WGA's WW1 line and upcoming rules set.
2. Could easily become a Death Fields faction.
3. Would be very popular with 40K players.
4. Most importantly these guys are awesome.
Look at these guys. Look at them.
You know you would start WW1 gaming just to justify getting these guys.
