Off Board Artillery

I keep reading rule 9.2, and i keep getting 'each increment may fire once PER turn'

So, if a scenario says a side gets 6*16 ... they may fire 6 increments each turn. not 6 increments total?

i keep thinking the rule is clear - so this may be a dim witted question
but i felt i had to check as its a lot of OBA rounds in a 36 turn scenario!
