Scuttling requires either nuclear warheads, or a gravity well and the ability to fall down it... neither of which is a given. (Fusion Plants are of need designed for safety, and tuning then into bombs is unlikely to work well enough to prevent reuse.
I guess some demo charges will also make the work.
Well, at the moment, that "code of conduct" is entirely hypothetical.
That's why I've always defended that the most important point here is the setting, incluiding those war rules on it.
Scuttling has been a time honored practice. Should it change over the next 30 centuries I have no way of knowing.
So had been surrunding the ship when keeping fighting would only lead to more casualitites. See my own post #43 in this same thread...
Not unless they have reason to believe they will escape, or be treated well in captivity and repatriated at some point. They will be provided with every means to assure that belief.
Once again, that would depend on war rules/tradition...
If I'm withdrawing, I'll have to fight not only the fleet that just defeated me, but with the addition of the ships I leave behind?

I think not.:nonono:
Those ships will of course switch missions should the need arise. Until then, they will fight relentlessly, to the very best of their design abilities. It only takes a single round to recall battle-riders and the vast majority of the well designed small fry, and other screening ships, will survive.
If you're not withdrawing I guess you will not shoot at the cripples, as if you keep the "field" at the end of the day you could recover them, and if you're withdrawing, those same escortss and fighters will be either covering the whithdraw or joining the rest of the fleet to jump away.
Also see that with RAW, no matter how much you keep firing to crippled ships, you won't scuttle them, as they will keep being easily repairable (unless you manage to score more criticals, in which case 1/36 such hits will vaporize one ship).
And usually, firing your own crippled hulls wil mean with more own deaths (that would probably be captured otherwise), something not too good for morale...
People swear that there are no tactics in a HG battle? I say differently. Deployment is, to a limited degree, tactical. Breaking off and withdrawing certainly is.
I would not call it tactics, while agreeing in your basics, but strategy.
I mean, in a purely tactical single engagement (let's say a TCS contest) whithdrawing means conceding, while in a more strategic game (let's say a TCS campaign), withdrawing may well lead to victory.
We are, each of us, into the hypothetical. I enjoy the academic nature of it and the dialog is fun.
Fully agreed.
