Most Ogre builds should Batter Bretts into submission... Brets charge range means nothing when a Sabretusk is stood in front of them.
Sure, Ogres do have the gear to smash Brets, but on paper anyway so too are Brets equipped to deal with Ogres.
It is also true that Brets suffer more than most armies from being redirected, but that is
warhammer. Most of the Bret lists I have seen on the interweb don't have many archers, so are really going to struggle against any army with multiple sabre tusk, harpy, skink or eagle (etc) units.
Math hammer:
Core only
11 x KotR FC = 288 pts
6 x Iron guts FC = 288 pts
Charge to the face by the KotR into the Guts
KotR strike
11 attacks hitting on 3 = 7
7 hits wounding on 3 = 5 wounds
Horses strike
9 attacks hitting on 4 = 4
4 hits wounding on 5 = 1+
1 save on 5+ = 1 wound through
total 6 wounds
Guts strike back, 4 models left
13 attacks hitting on 4 = 6 hits
6+ hits wounding on 2 = 5 wounds
5 saves of 5+ = 3+ wounds
3 ward saves of 5+ = 2+ wounds
Combat resolution:
Brets: charge (1), banner (1), ranks (2 or 1), wounds (6) = 10 or 9
Ogres: Banner (1), wounds (2 or 3) = 3 or 4
Brets win by 7 or 5
Assuming KotR charge which on paper they should, in isolation for equal points they steam roll Guts. Of course if the knights fluff their attacks the guts could end up winning, but the knights will most likely be steadfast. If it becomes a grind fest all bets are off for the knights.
would love to take on Anthony's Orge army of doom!
No Ogre army of doom, just happy bellies and good karma
