"Awwww, look at this little guy! What are you? Are you lost? Haha, I think he's scared!"
"SPRINGER, THAT'S A B-"
Small and nimble, tank-like vehicles. This type actually encompasses a wide range of vehicles that are however all commonly referred to by the same name - Goliath. The name originates from a single model that was used by humans in the past, but has become a descriptor for the entire type of modern mobile mines.
SentienceA Goliath's purpose in life is simple - seek and destroy. While their ancestors were remote-controlled, the modern counterpart is sentient and fully autonomous. They are not built in factories, but instead assembled in workshops, using spare parts and a very rudimentary faux-AI. The "source" for this type of AI is widely available and usually installed in old, wiped AI Cores.
OperationLacking a will of their own, Goliaths without orders just act in a seemingly random manner. Most of the time, this means that they simply nap to conserve energy, but sometimes they can be seen zipping around. This includes driving underneath other vehicles, which tends to give frights to their allies. They know friend from foe when explicitly told and can follow simple orders. When told to destroy a target, they are capable of being sneaky, but can also simply approach it as quickly as possible. Once they reach a target vehicle, they will try to get either under or behind it and trigger their explosive charge. This causes the Goliath to blow up and damage whatever is nearby severely. Effectively, this also kills the Goliath, making them single use.
Other UsesSome Goliaths live longer than their peers by being used for scouting operations instead, which they are quite suitable for; their small size and relatively silent movement makes them hard to detect. Sometimes, vehicles get sentimentally attached to their Goliaths. While generally, they are not seen as capable of thought or emotion, some will insist that "their" Goliath has a personality and keep them around as pets. In other cases, vehicles simply feel qualms about treating them as a disposable weapon.
Typically, Goliaths are powered by electrical motors. Their long-lasting batteries are charged by hooking them up to another vehicle's engine or an electrical outlet. They move about on caterpillar tracks, which allows them to traverse all sorts of terrain - though their small ground clearance means they get stuck often.
Weapons & Armament
The main offence of a Goliath is their explosive charge. This charge is installed in their body and can be detonated at will. The power of the detonation can vary. Depending on the size of the model, the explosives loaded amount to between 100 kg and 350 kg. The heavier models are capable of destroying even large tanks easily. Other uses are blowing up strategic points of interest like buildings or bridges.
Armor and defense
The armour on Goliaths is not designed to withstand enemy fire, and assembled in a way that doesn't impede the force of the explosives - at detonation, its seams burst with nearly no resistance.
Communication Tools & Systems
Goliaths cannot express themselves in the way other vehicles can - they lack voiceboxes. Instead, they communicate via radio, in a simple, nonverbal language. This language can be a very simplified English, for example, or other languages depending on the vehicle's origin.
Like their tank cousins, these vehicles have optics and audio receptors to perceive their surroundings; they however lack a sense of smell.
Several different models with distinct specifications exist - the above data is an example of a typical, average Goliath.
