This article is about the Sabre unit. For the Orbital Drop Shock Trooper, see Echo One (ODST).
Echo One was a YSS-1000 Sabre that fought during Operation: UPPER CUT alongside Noble Team. The Sabre defended Anchor 9 when the station came under attack of Covenant Type-27 Banshees and Type-31 Seraphs, then participated in the assault on the SDV-class heavy corvette Ardent Prayer. Echo One was the only Sabre that did not infiltrate the topside hull of the corvette.[Note 1]
