Couldn't they have modified the ship like some other Dropships, say the Leopard, to carry a Battalion of Mechs by converting the other bays into Mech Bays?
The standard Fortress class dropship does not have a Sniper class artillery piece but a Long Tom artillery piece.Apparently he think that the sniper artillery gun is some kind of a magic wand, instead of an almost useless weapon against moving mechs and vehicles. It is really useful only against static emplacements or if you don't know where the shot will land.
It is also somewhat peculiar how he threatens to use the single Fortress as some sort of magical instrument that will annihilate the opposition. Sure, Fortress is somewhat better armored than the rest. But not all that well. Single Atlas has (in total) more armor than what single side (which is the part that would be attacked) of a Fortress has. A lot more. So it is quite clear that a determined mech or vehicle assault would be the end for the Fortress. Sure it would likely take more attackers down with it than what Union or the like would but it still would be a easy pickings. But it is a plot tool so i guess that just has to be accepted.

You would think there would be at least one Overlord somewhere. I know these folks are poor but really.Especially since, based on the about 11 Unions & 19 Leopards in the final invasion cinematic, the Restoration is dropping with about six battalions.
A Fortress matters in that context, but its not quite the "oh crap" moment the story tries to sell it as.
I've double checked the times he talks and he says battalion of mechs.
It does not carry an army. Just a battalion. And a mixed one at that. Meaning the offensive punch consists just of 12 mechs and 12 vehicles. And it is very unlikely that full battalion would remain operational - after all the crew of the Fortress had already mutinied against the Commodore. And the single arty piece it carries changes very little. Given that Kamea's army had come down to assault static defenses of the capital, they too would have arty - and there really is no better target for artillery than a grounded dropship... So even in the odd case it would have landed it would have led to a trashing - just not the way implied in the story.Also, note that the Fortress has a lot of firepower which would be hard to deal with if most of Kamea's army is light mechs and vehicles. Which is likely the case since this is the Periphery. Kamea's army is likely split across different parts of the planet while that Fortress can drop down and deploy its army to crush any one battalion of the restoration.
