Hide (forest): This unit can hide in forests until enemy units get too close.
Rat Ogres is a Skaven Monstrous infantry unit in Total War: Warhammer II. Patchwork creations of pure brawn and unthinking rage, they charge with the desire only to destroy.
The hulking monstrosities known as Rat Ogres are one of the most successful of Clan Moulder's numberless creations. The Master Moulders have found the perfect blend of death-dealing creature through a mixture of foul crossbreeding and dark sorcerous surgery. In their artificial making, many beasts are literally stitched together, the impossible feat accomplished through the fusing powers of a powerful Warpstone-derived balm, the infamous skalm. The Rat Ogre combines the speed and ferocity of a Skaven with the sheer brawn of an Ogre. Somehow the desperate hunger of both races has been magnified as well - for the Rat Ogre is truly a ravenous creature, forever seeking to gorge its fill on fresh meat. In battle a Rat Ogre pack is horrifying to behold, becoming wholly consumed by an insatiable instinct to kill, rip, and tear, and it takes a Packmaster to steer their ferocious charges. A Rat Ogre pack moves with great speed, their misshapen bodies made entirely of straining, bulging muscles, teeth, and claws. The snarling rage of a Rat Ogre pack colliding with an enemy unit resounds across a battlefield, as the towering creatures splinter shields, snap bones, and relentlessly pound any and all opposition.
↑Armour-Piercing: The damage of armour-piercing weapons mostly ignores the armour of the target, making them the ideal choice against heavily-armoured enemies. They are often heavier and attack at a slower rate though, making them less efficient against poorly-armoured targets.
↑Frenzy: Units with frenzy cause more damage while their leadership is high.
Rat Ogres are the equivalent to Shock Cavalry: fast, fragile, and boasting a massive charge bonus. Do not send them to engage the enemy head-on, as they will die surprisingly fast in combat. Instead, send them after light enemy targets such as archers, or have them work the flanks while Clanrats and Stormvermin keep the enemy engaged. They are very cost effective when compared to other Skaven units and should form a sizable part of your army. They are especially effective against slow, heavily armored factions such as Chaos, Dwarfs, and Lizardmen.
