Here you should find a list of common, across the board terminology. Please ask if you have questions. Also feel free to add any you think should be included but are not.
H2H or HtH is hand-to-hand (combat)
=I= is the Inquisition (quite clever, that one!)
chimeltavets (or variants thereof) describes IG veterans in chimeras armed to the teeth with meltaguns
FNP is Feel No Pain, which is a
USR, or a Univeral Special Rule (from the main rulebook); many of these are abbreviated.
FOC is the Force Organisation Chart,
WAAC is 'win at all costs',
RAW is 'rules as written' as opposed to
RAI which is 'rules as interpreted'.
++ is short hand for invulnerable save.
++ for a save also can be an Orwell reference. In Newspeak a thing can be "doubleplus good". So a 3+ save is good, but a 3++ is obviously even better. ;)
Aka, 3+ saves can be negated with AP, 3++ however is an invulnerable.
