I see 3 Sov captains. One initially, 2 in reinforcements.
Fire in the Steppe used the counters from Eastern Front Deluxe. I don't recall addition Soviet leadership, but I'll check again.
As a work around, you could do 2 things/
- Draw the first 3 captains. Turn on their IDs. Pull one of each from the normally random counters. Flip them as appropriate to match the ones drawn. Turn off the IDs. Delete the counters you drew randomly. then draw the remaining captains from the random leaders.
- Use the Workers & Peasants leader extension.
I'll let you know what I find. BtW: The ILS only has 3 captains in the mix.
