What makes sense to me, given that (a) I'm likely to increase the command size to 6-battalion eventually (300-1,500) and (b) for an old guy, I'll be improving fairly rapidly, is that the elite force *was* battalion size.
Something (what? It's a mystery!) happened, and the former captain took command of the forces and led them to a horrendous defeat where we suffered horrific casualties and I was wounded (and him killed), and while the harm has healed, I'm still getting back up to speed.
That explains (a) how the former captain died. (b) why we trade in military force. (c) How I can be so old and improve so fast. (d) how we have capacity for the forces to be arriving.
As this impacts on your ship and character, feel free to veto/amend this, but thought I'd suggest it.
Looks good to me!
Your security force acting as your bodyguard is basically pointing a massive finger at me saying you either don't trust me to do my job well, or you think I'll betray you. You can totally do that, but be aware there will be friction between the groups as well as the characters.
I would think that having a squad of guards personally loyal to the captain would be appropriate in setting, and not a big insult, though I can certainly see how it would rub the Security Chief the wrong way. Also, of course, given Father's mysterious death, Lady Penelope will try not to rely too much on even the trustworthy old guard - even though you took a hit in the Incident, I won't be able to completely trust the security team that let Father die.
I'd expect rivalry and friction to result, of course :) part of the fun!
The militia is just a militia - it's the crewmen who know which end of a gun goes 'bang'. They just get drafted in when there are riots, otherwise they do their normal jobs.
A few things to perhaps consider:
1) What happened to your mother (I suggest either still alive, or only relatively recently deceased.)
2) How strong *is* your claim to the ship? Is it simply you were here first, or are you the oldest? The one named in his will?
3) Why wouldn't you have been raised on the ship?
1) Mother I hadn't considered. I will think about her, but my first instinct is to have her back home on the planet Lady Penelope grew up, anxiously waiting for word.
2) I think that the good claimants fought over the inheritance, and are dead or indisposed. I am a lesser child, but distantly loved by Father, and is technically the rightful heir (after Father's siblings and older children got themselves killed). Wait - better! I'#m not a legitimate child, so there is some dispute as to the status of my claim even though the old Lord-Captain acknowledged her as his daughter and heir. How does that sound?
3) Because I'm a child by a lover who lived on a planet the ship came past every once in a while. The Lord-Captain loved Mother dearly, and spent a lot of time with her when he was on-planet. And very much enjoyed his infrequent visits with me, too. But Mother was too important on her world to leave, and Father had his other lovers and wife to keep him happy while he was away. I was never seen as a real part of his dynasty, except (according to his surprising will) by him.
