This article is about the SPARTAN-III team. For units that were designated "Echo", see Echo Team (disambiguation).
Team Echo was formed from SPARTAN-IIIs that were voluntarily recruited circa 2539.[Note 1] They were trained at Camp Currahee under the watchful eye of Lieutenant Commander Kurt Ambrose on the highly classified planet Onyx.
In 2545, the majority of Beta company (300 in total) took part in Operation: TORPEDO, a plan to disrupt Covenant fuel supply lines. After the completion of the operation, all members of this group, along with most of Beta Company, were pronounced KIA as the explosion killed almost every SPARTAN-III.
