Is it possible, that the greeks never adopted the roman term pilus and insisted to use the term triarius?

A tombstone from Apamea may help here. It is that of Baebius Severus, an immunis in the century of the pilus posterior of the 5th cohort of legio II Parthica and is bilingual, Latin and Greek. The Greek version of the centurion's title is πίλου ύστέρου, so pilus could be transliterated into Greek.

If you look at the Strategicon most technical terms (especially the orders) are still in the original Latin even though some Greek authors in the past translated Latin ranks into Greek. Latin was the language of the army and I guess some Latin terminology was never translated into Greek equivalents?
