Training dummy

A vital tool in the training of young Autobot cadets, training dummies are used to practice close-quarter combat. Modeled after Decepticon melee specialists, training dummies can be found in practice rings across Iacon. Oddly enough, they're most vulnerable to laser-based weaponry.

Transformers: War for Cybertron (DS)
Air Raid regularly used training dummies when Ironhide sent him raw recruits to train.
