Since the first flight of the Gyrocopter, Engineers have been seeking ways to upgrade its payload. There were times, such as when Greenskin invasions filled the valleys, swarming up a mountain's flanks to besiege a Dwarfhold, that Gyrocopters buzzing around the flanks just wasn't going to break up the attack. With some reconfiguration, and by losing the heavy weight of the steam gun, the Engineers' Guild were able to significantly increase the size and number of bombs carried. Thus was the Gyrobomber invented. Armed with their impressive bomb racks and a nose-mounted clatterygun, the Gyrobombers stream over the Dwarf battle lines seeking to obliterate the foe's largest formations. Already, several flying formations have become famous - perhaps most notably the Skyhammers from Zhufbar and the Blackhammer Bombers and Karaz-a-Karak.
↑Anti-Infantry: Anti-infantry units have an advantage against targets that are smaller than a horse. This advantage can be a damage bonus against small targets, superior weight used to smash through lighter enemies, or an explosive attack from range that effects a large area.
↑Armour-Piercing Missiles: 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.
↑Armoured: Armoured units can block damage from any source apart from Armour-Piercing damage.
↑Improved Bombing : Like a rain of mighty hammer-blows from above, this unit drops more than one bomb at the same time.
