The saints Procopius (in armor) and Sabbas Stratilates.

The Wikipedia has: “Procopius of Scythopolis (died July 7, 303 AD) is venerated as an early martyr and saint. He was a famous ascetic as well as an erudite theologian and philosopher.[1][2] Eusebius of Caesarea writes of his martyrdom, which occurred during the persecution of Diocletian, and states that “he was born at Jerusalem, but had gone to live in Scythopolis, where he held three ecclesiastical offices. He was reader and interpreter in the Syriac language, and cured those possessed of evil spirits.” Eusebius writes that Procopius was sent with his companions from Scythopolis to Caesarea Maritima, where he was decapitated. Later legends make him a soldier saint, or an ascetic, or a Persian, or a prince of Alexandria. One story has him slaying some 6,000 barbarian invaders simply by showing them the cross. One legend, similar to that told of Paul of Tarsus, makes him a persecutor of Christians named Neanias who was made duke of Alexandria by Diocletian. On the way from Antioch Neanias experienced a vision and declares himself to be a Christian.” and

“Saint Sabbas Stratelates (Sava Stratelat, Sabas Stratilat, Savva Stratilatus), Sabbas the General of Rome (died 272, Tiber River, Rome) — early Christian warrior saint and martyr, was Roman military general under emperor Aurelian. He is the 'twin' of Saint Sabbas the Goth. His martyrdom was followed by 70 Roman soldiers. Saint Sabbas Stratelates came from a Gothic tribe. For his bravery he attained the high rank of military commander or stratelates, and he served under the Roman emperor Aurelian (270-275). From his youth, Sabbas was a Christian and he fervently followed the commands of Christ. He helped the needy, and visited Christians in prison. Saint Sabbas had the gift of wonderworking, healing the sick and casting out demons in the name of Christ. When the emperor learned that Saint Sabbas was a Christian, he demanded that he apostatize. The martyr threw down his military belt and declared that he would not forsake his faith. They beat him, burned him with torches, and threw him into a cauldron with tar, but the martyr remained unharmed. Looking on at his torments, seventy soldiers came to believe in Christ. They were beheaded by the sword. St Sabbas was thrown in prison. At midnight, while he was praying, Christ appeared to the martyr and shone on him the light of His Glory. The Savior bade him not to fear, but to stand firm. Encouraged, the Martyr Sabbas underwent new torture in the morning, and was drowned in a river in 272.”
