Translation: Built for Emperor Nerva Trajan Caesar Augustus Germanicus Dacicus, by the testamentary engraving of Marcus Julius Secundus, former first centurion. Julia Grata, daughter of Gaius, his wife and heir. [Functionally identical Greek and Latin texts] (Trans. Christopher B. Zeichmann)
Commentary: Julius Secundus does not name which unit he served in, but it was likely in legio VI Ferrata, which garrisoned in Arabia after the annexation of the Decapolis to the new province of Arabia in 106 CE. There is, to my knowledge, no evidence for the title of chief centurion in auxilia.
Provenience: Gadara, Arabia (Umm Qais, Jordan) 106-115 CE
