never heard them referred to as "chevrons". Possibly in a formal reference

Chevron : bent bar of an inverted V shape (Shorter OED-CD)

I used chevron in case the word stripe was unfamiliar ...and I did not want them confused with a straight line "hash mark."
And, yes, the word chevron is used in some military publications, usually (at least ones I have access to) that are from earlier times.
OK?
wow
