Typical Patlabor violence is here. If you're not already familiar with the Patlabor series, then you could liken the violence in this show to the 80's Transformers kids show. It's very mild and it's all machine-based, though, large guns, missiles, and other weaponry are occasionally used. The show is also devoid of any blood or injury detail.
A type of artificial fluid is used to resemble blood in one episode. However, it is quickly revealed to actually be fake blood.
