I modded in a new military troop.
It involves these changes:
[MATGLOSS_STONE:DWARF_STONE]
[NAME:earthen dwarf][COLOR:7:7:1][TILE:220]
[SOLID_DENSITY:30000]
[MELTING_POINT:100]
[BOILING_POINT:150]
[VALUE:1]
[ITEMCORPSE:STATUE:NO_SUBTYPE:STONE:DWARF_STONE]
On my new, heavily modded game, I included the above changes to make the dwarves more thematic--they're made from the earth itself, blah blah, so their stone form dissolves away back into the ground when they die.
So, anyway, in the second year, the orcs came to play and I hadn't built any defenses. In a last-ditch effort to take out the 16 orcs, I recruited all 48 of my dwarves and threw the recruits at the orc squad.
I had forgotten about the above modding.
The was a chain of Urist McDwarf, Dwarf has frozen to death.
Boiling points, being the highest temperature a material can reach (in-game), will lower the tile temperature to the boiling point, freezing anything if it's cold enough. When a dwarf of mine would be killed by the orcs, the next one behind him would also die--but so would the orcs.
SO WOULD THE ORCS.
I savescummed, made 8 peasants and soap makers into recruits, grouped pairs into 4 squads, and spread their squad stations around the entrance of my fort courtyard.
When the orcs came in this time, the recruits, running in a staggered formation due to their spread stations, suicide-bombed the infidels.
4 of my saboteurs exploded 15 orcs to death. The last orc retreated off of the map, chased by the remaining 4 saboteurs.
Bwahahah.
Bwahahahaha.
