How does a repatriation bond get put into effect? That’s the most ubiquitous combatants’ rights declaration I know of in the OTU.
It might go more smoothly than we think. Conflicts with organized mercs are a bit like war with allied nations : let's say A is at war with B, and hires C as mercenary reinforcements for one year of operations. For twelve months, C is thus a co-belligerent, whose interests align with A's but only for the duration of the contract.
After one year, C does not seek/accept a renewal of its contract. It obviously has to tell A in advance so A's forces can relieve the mercs. But it also has to tell B, because if it doesn't B might attack the mercs or hinder their repatriation, in which case C would have to fight and endure losses for free.
Now that is knows about the repatriation bond being called, nation B certainly won't complain too much - a part of the enemy's forces are giving up the fight willingly and in exchange of nothing beyong return of merc prisoners. Pretty good deal, victory seems closer than ever. Why waste men and weapons and energy on attacks on the C mercs, and risk them reconsider their decision to leave ?
A will be quite unhappy, but what can they do ? Preventing the evacuation or claiming the repatriation clause is null and void is not an option. B knows the mercs are leaving, and will not attack them. As for the merc company, what's to stop it from letting A know the full force of its displeasure by leaving B's forces pass through their positions, or provide them with critical info on A's forces ? After all, there's no deal between A and C anymore, and A is in breach of its contract.
For that same reason, I tend to think most organized merc units would have a code of conduct of their own (like no massive war crimes regardless of bonus), as it would only endanger "company assets" and force them to fight for free when the contract ends. At this stage, I see the merc unit as an enterprise providing corporate violence to would-be clients, and operating along lines of acceptable physical/legal risks (which means protecting its "privilege" of walking out of any war at the stipulated date or in case of a client abusing the contract).
