Artillery in Auxiliary Cohorts

[CaesarAugustus]

Interesting. Do you have more references about this?

The account is at the end of Constantine Porphyrogenitus's 10th-century De Administrando Imperio, online here. Not the most authentic source, perhaps! The 'arbalasts' are being used by the people of the city of Cherson, rather than Roman soldiers, but it suggests that it was possible. We discussed the episode here.

I don't know how plausible the story is. However it is known that the ballistae were used on the city walls, so it is plausible to think they were used by urban cohorts or even auxiliaries. But other than that, I am not aware of any auxiliaries equipped with siege or field artillery.
