I would say, having deployed on two tours of Bosnia and nine and a half months in Afghanistan, that the regulations, particularly the Queen's regulations and orders and the code of service discipline, continue to apply, and the expectation is that they will continue to be applied by the chain of command.
I would also assert that this gives, at one end of the spectrum, the resources necessary to a commander to effect discipline. On the administrative side, there are always administrative entities and structures in place that allow for resolution.
I might assert that formal ADR processes are not always conducive, but certainly the expectations in terms of what is applied—sexual harassment guidelines, all of those things—remain extant and are necessary for effective discipline on any deployment.
