IMPLIED VEXILLATIONS IN ROMAN INSCRIPTIONS

In treating of Robert Saxer's work, Untersuchungen zu den Vexillationen des Römischen Kaiserheeres von Augustus bis Diokletian (Studies of the vexillations of the Roman Imperial Army from Augustus to Diocletian), Anthony Birley (https://www.jstor.org/stable/27684466#metadata_info_tab_contents) remarks that 

Birley's mention of well over "42 such cases" in which the word vexillationes (or vexilla, etc.) is implied is significant.  I had found one such and used it to counter the argument of Dr. Linda Malcor that vexillations could not be implied in the Castus inscription

(https://mistshadows.blogspot.com/2022/10/proof-positive-that-vexillations-are.html).  I now know there are many more inscriptions that clearly refer to detachments, even if the detachments in question are not specifically described.
