Orc Big 'Uns

Orcs expect the smaller greenskins to run awayy and it doesn't really surprise them when they do. The sight of fleeing Goblins and Snotlings simply reminds the bigger and bolder Orcs why they are best. Consequently when a Goblin unit. Snotling Swarm or Snotling Pump Wagon is destroyed, breaks or flees pat. Orc units do not need to test for panic. See the Viarhammer rulebook. pages 80-81

Subject to animosity

Big ‘Uns : The meanest and strongest Orcs in a tribe often fight together in a single mob. Sometimes they fight as Boar boyz, sometimes on foot - it depends on the tribe.
Choose up to one unit allowed in the army to upgrade to Beatins and pay the appropriate points. This may be a unit of Orc Bon. Savage Orc Bon. Orc !kat Bos-z or Savage Orc Boar Bon. Whichever type of unit you choose to upgrade you must have at least as many normal models of that type in other units before you take the Bigtns. You may only ever have one unit of Biatins in any army. A unit of Miens may carry a masa standard wonh up to 50 points. This is in addition to any magical banners that would normally be allowed to units of that type. So, for example. if your Bigtris are Boar Boys then both they and one unit of normal Boar Bon may take a magic banner.

Choppa: The average Orcish cleaver or dub is a big, crude affair much like the Ore on the blunt end of it. This is the standard armament for Orc foot troops and characters, and is carried instead of a normal hand weapon. Orcs refer to such weapons as 'choppas. Such a chunk of metal would he difficult for a human to wield in one hand but Ors are muscle-bound beasts with fists as big as a man's head (and only marginally more dexterous).
An Orc warrior on foot armed with a single choppa adds +1 to his Strength in the first round of a combat when he charges. This bonus don not apply if a weapon is carried in each hand, or for Boar, Chariot or monster riders - in such eases the weapon's natural brutishness is cancelled out by the difficulty of wielding it.
The Choppa bonus applies to character models on foot that are armed with a single ordinary non-magical choppa. It does not apply to individuals armed with magic weapons as they receive the appropriate magical bonuses instead.
Note that the bonus armour save for using a hand weapon and shield does not apply to an Orc wielding a choppa. Foot models with a choppa in each hand (additional hand weapon) do get the normal +1 Attack for having two 'hand weapons', though they lose the +1 Strength on the charge.
