Surprisingly they somewhat explained why a volus would be in the battlefield. ''The volus homeworld, Irune, has a high-pressure atmosphere that supports an ammonia-based biochemistry. To survive on other planets, the volus must wear pressure suits and breathers or, when facing combat, specially sealed armor.'' So at least they kinda explained how a volus could be fighting against a brute. Afterall the only volus we've met during the game have been civilians.
