It never rains but it pours. The first company to release styrene figures from the Civil War was Dragon, which released a terrific set of Union soldiers in 1/32nd scale some decades back. Unfortunately, they never followed up with the promised Confederate infantry, as they apparently didn’t feel the sales merited it (hard to understand, as I literally bought a case of them for myself).
However, recently two different companies have suddenly released figures from that era – Masterbox and now ICM. ICM, in my opinion, has taken the lead in this arena by releasing BOTH Union and Confederate troops.
