BattleTech: The Animated Series - Season 1 Episode 3 Warriors of Light and Steel

We see Nocholai conquering another planet in the introductory scenes. Adam Steiner leads his forces to train at a holographic training facility on Romulus. Cero thinks this is a waste of time and disagrees with Adam. The Clan mechs invade, and the Sumerset Strikers are attacked by Toad elementals. The strikers defeat these only to be met by three clan mechs led by Nicholai. Adam challenges Nicholai 1 on 1, and quickly axes a mountain to cause an avalanche. The clan mechs must fire at the falling rocks and the Strikers escape. This infurates Nicholai. The dropship is captured by the clan, but Sakamoto discuises the weapons so it looks like an innocent trade dropship. The Somerset Strikers attack the clan forces. They seem to have won a small vicotry and pull out. During the retreat Cero attempts to save some loose humans. His mech is obliterated by the clan mechs. He fires his escape pod and is captured by Nicholai Malthus, though Adam leaves Romulus believing that Cero is dead.
