mortars - who has priority (per rules)

Please I hope this will be only a quick clarification and then reminder forwarded to admins.

When can a squad named mortar(s) insist on and rely on admins to obtain mortar assets when another squad is using them?

Rule check:
(Only specific mention or mortars in rules is regarding placement location on Muttrah)

I have to admit I know it's not in the rules but was always under the impression that a squad named mortar did actually claim the mortars.
Having a dedicated mortar squad just seems the right way to go maybe?
I stand very much corrected though and apologise.

Would it be possible to add this to the rules for future clarification and to prevent any more confusion please.

Fair enough, that's cleared things up.
