W011-Speaker-UCU

Possibly the least expensive AA to see widespread use, the W011-Speaker-USU (Urban Combat Unit), or 'Woll' as it's often corrupted to, is also probably the simplest. A slightly flattened ball with legs and two missile pods. Equipped with retractable wheels (although in older models, these have often scrapped due to wear and tear), an OS and little else, there is an old joke that 'you can field five Wolls for the price of a real AA'. However, the Woll's has served in battle well beyond its expected selling date, due to its absurd price and surprising effectiveness in battle. The Woll, whilst slow, can turn a full 360 degrees in a surprisingly short period of time. Coupled with its short stature, homing weapons and low center of gravity (resulting in a reduced chance of overturning at higher speeds), the Woll is excellent in its chosen environment; the city. Able to use cover effectively and avoiding rough terrain that'd hamper their speed, Wolls alone have won many a siege, with their simplistic control system allowing nearly anyone, trained in AA piloting or not, to make use of them.

However, the Woll's performance outside of its selected domain is less than stellar; the Woll is not coated with Anti-Dust Paint and often breaks down in the field. It also has difficulty moving over rough terrain as its wheels are not equipped for this and its gait does not allow for its legs to lift high off the ground. Whilst a Woll can lie without use or maintenance for a significant period of time and still function, it needs to be serviced after each battle due to the strain on its joints. Wolls are mostly generator with no room for armor or safety mechanisms and must use their small size and agility if the pilot wishes to see the end of the battle.
