I think that different structures would produce different things, in addition to what's already stated above. For example, trainable units (i.e, specific monsters or types of soldiers) would come from certain buildings (i.e, Slimes from a Slime Pit or human foot soldiers from a barracks).

Both the structure and unit would have certain requirements to build/train them (i.e, spending resources like captured human women OR having a mamono civilian couple and fully upgrading a Tentacle Forest, thus granting access to the coveted Treasured Child Tree; special units would also require either certain other structures, upgrades, or territory traits: using slimes as an example, Bubble Slimes would need at least a second-level mamono castle, Red Slimes would need an upgraded Slime Pit, and Dark Slimes would need your Slime Pit to be in a Demon Realm)

For humans, it would be easier than monsters to make soldiers, since they'd be overall weaker: go to your castle, spend food+water resources to produce human workers, have them populate the castle (turning them into a resource called trainable humans), go to your structure, spend resources and get trained soldiers after waiting for a little while. Just remember that defeated soldiers can/will turn into resources for mamono, and you will still need workers available to collect other resources (food, water, wood, iron, gold, etc.).

Finally, once you've fully upgraded your castle, you can make your super-soldiers (for game balance, you may only have one of each of these at any given time). For humans, it would be a Hero Warrior (Barracks), Hero Ranger (Shooting Range) or a Hero Spellcaster (Arcane Tower). For mamono, it would be a Lilim (Mamono Castle), a Baphomet (Church of Sabbath), or a Dragon (Dragon's Den). (Note: these would not be the only ones; other factors may make others available.)
