HoMM VII Haven Units – Haven faction units from the seventh installment of Heroes of Might and Magic.

They look good, but I think crossbowmen should be the second-tier unit. It would be possible to move the upgrades and non-upgrades into the game, and then finish the alternate upgrades, coloring the creatures red.
UPD: Did I understand correctly that they are all moved to one tier, instead of swordsmen?

Mm, no, spearmen are tier 1, crossbowmen are tier 2 (I've wanted to replace the useless peasants for a long time), and originally, a different mod was planned... which was supposed to be called "spearmen from Heroes 6 and 7." The legionary should be an alternate upgrade, and I think the watchman and praetorian are clear, but due to the difference in scale and units of measurement, it turned out to be nonsense.
