Not sure if it was already discussed, tho I thought could be worth asking - how about making new pedia article type to show discovered soldier types? In OF there was no need for that, as there is only one soldier type for the whole game.
But today many mods use ability to define different soldier types, and they could be very different in stats (max, min, caps) and available armors. There could be a place to describe some lore too, as modded soldier types could appear as even non-human beings.
Many mods workaround not having specific article type by making just a regular text peda article. But it is not really handy - lack of structure and it can't use values from rulers directly, this you have to change translations with your balance changes. Stat for nerds could be a nice for that article, showing all information in great details. What would you think?
