The Earth Liberation Army, or ELA, was a force on Earth commanded by Grigori Tarkanovsky that fought in the Tarkanovsky Revolution. The army was known for their grey Tarkanovsky Jackets.
Initially crushing the Centro Systems forces, the ELA was defeat by the founding of the Centro Military whose training and experience far outweighed their own. Upon their defeat, and the execution of Tarkanovsky, the army was effectively disbanded.
