How common were battle cries in European heraldry?

by Plicated

While randomly browsing Wikipedia I stumbled across a section on Polish coats of arms, it seems like some of these coats of arms had specific battle cries associated with them. Was this something unique to Polish heraldry - which, from what I understand, is quite different to its Western European counterpart - or was it common in other parts of Europe as well? If anyone is able to tell me more about this I'd be much obliged.

Thank you in advance.
