Antonius was dismissed from the Praetorian Guard by the emperor Galba, likely for disloyalty,[5] but appears to have regained imperial favor after Galba's fall, and was able to resume his military career afterward.[6] It's likely he acquired his military decorations either during the rebellion of Gaius Iulius Vindex against the emperor Nero, or during the fight against the Pisonian conspiracy in 65.[7]
