Anyone in any job, civilian or military, will know that little sentence on the contract of employment 'and other duties as required'. It does appear to affect military personnel more, for sure, but I still say that Bulwark's crew are doing an unpleasant task for day after day with no relief in sight, with the knowledge that what they are doing will have absolutely no effect on the causes, and will not stop it happening. If anything it will only encourage it to happen more and more. It is June and I expect they'll still be doing it in September while the politicians continue to shake their heads sadly and wring their hands while the traffickers get richer and richer.
If that's acceptable, please say so.
