Practice relating to Rule 66. Non-Hostile Contacts between the Parties to the Conflict
Croatia’s Commanders’ Manual (1992) states:
Local interruptions of combat and other arrangements can be concluded between opposing forces. At lower levels, such arrangements can be very simple and concluded orally: voice, radio, bearer of a white flag (flag of truce). At higher levels and for longer lasting interruptions of combat, written agreements shall be concluded.
