(Increased size of all strings to 31. Problem: DO uses strcpy() without checking string length: overflow! -> Solution: Set byte after string to 00 so that our example dump causes no overflows ;))

.ARM (army) files contains a list of regiments, their status, and some army data and statistics. The same format is used for multiplayer armies, single player mission enemy armies and save games. Edit with Mikademus' DOS WH2EDIT editor or Ghabry's forthcoming multi-platform Wh32Edit.

Regiment attributes

Regiment attributes are physical and psychological abilities or disadvantages of entire regiments. Attributes are stored in the regiment block at bytes 16-19. The different values are flags mapped to bits in four bytes (thus 32 unique attributes are possible).

Transcluded from DO/ARM/Regiment attributes

Note: The Bits in this table are going from lowest to highest bit. So the lowest bit is 1 and the highest 8.

Bit BYTE 1 BYTE 2 BYTE 3 BYTE 4

Flagellants, steam tank and most undead have this

Function basically undeterminable... :(
Guess and/or untested
I changed "psychology" to "attribute". I originally used the term psychology when I started mapping out the .arm files, and I thought that only the Warhammer psychology stuff (like hatred, saga animosity, fearless, etc) were stored there. But as also physical stuff like terrain striding etc are represented here "attributes" is a more descriptive term. Mikademus 23:24, 18 September 2008 (UTC)

I have started colour-coding the above table. Since it has been a while I am not certain which attributes I definitely determined and which I merely surmised. Ghabry is the the current authority on unit attributes, and I hope he will be able to complete the chart. Mikademus 12:43, 19 September 2008 (UTC)

Certain or likely flags

Flag #9 (byte 2 bit 1): In DO only skeletons have this set. It seems to be the undead army list rule that skeletons (which are immune to fear and don't take rout tests) take additional wounds from being pushed back

Flag #24 (byte 3 bit 8): This is an adaptation of Warhammer's special Screaming Skull Catapult rule. The Screaming Skulls fired by the catapult cause fear, so if even one casualty is dealt the receiving unit must take a rout test. Since Hand of Nagash also has this is is surmised that is is also used to give extra oomph to his attacks, and in extension, to the attack of any unit with this flag.

Uncertain flags

Flag #3 (byte 1 bit 3): Only goblins have this set. It could simply to indicate race, or it could be to indicate goblins' racial traits. The WHTTv4 rules about goblins are:

Races/Warhammer/Goblins/WHTT4

logo4thedminimalrn6.png

Relevant WHFB TT goblinoid rules v4. Goblins

  • have animosity toward other goblinoids
  • hate dwarves (and gnomes)
  • fear elves (of numbers > half the goblins)
  • and some special stuff about being led by snotlings and substituting spells.

Flag #4 (byte 1 bit 4): Only elves have this set. It could simply to indicate race, or it could be to indicate elves' racial traits. The WHTTv4 rules about elves are:

Races/Warhammer/Elves/WHTT4

logo4thedminimalrn6.png

Relevant WHFB TT v4 elves rules. Elves

  • are feared by Goblins if less than twice the numbers
  • have double encumbrance from armour

Wood elves

  • Suffer no movement or manoeuvre penalties in wooden areas
  • have 6" longer range with bows
  • and some special stuff about being substituting spells.

Are elves equipped with the same longbow (missile weapon type) as f.i. Helmgard Longbowmen? If so then we know that at least the additional distance rule applies.

Flag #18 (byte 3 bit 2): Only wraiths have this set. It could simply to indicate race, or it could be to indicate wraiths' special traits. The WHTTv4 rules about wraiths are:

Races/Warhammer/Wraiths/WHTT4

logo4thedminimalrn6.png

Relevant WHFB TT v4 wraith rules. Wraiths

  • are immune to all psychology (seems not to be true in DO)
  • cause fear 12" +2 in all living creatures regardless of size
  • can only be damaged by magic, magic weapons, daemons, or undead chill attacks
  • have chill attacks that automatically cause 1 wound, no save and no armour
  • are bound to a particular place and dematerialise if they leave this zone or the thing they're attached to is destroyed
  • can pass through any material obstacle unhindered

Flag #12 (byte 2 bit 4): This units can't fight in Closed Combat and can drive over other regiments while charging.
