You just want to make this a normal real world army operation but instead of having bullet guns we have laser ones. The ideas were not stupid, even if they had a small chance of happening and what's the problem with that anyway? You see a shit ton of special predicaments with a very unlikely chance of happening in the comics and TV Cartoons. Why should this Rp be about generic troopers with a generic objective? 

One more thing, if we go with your plan and have a "smooth crash landing" thousands of troopers are bound to survive it. And taking into equation that we belong in different divisions and units, we would be separated given separate orders by our superiors. The whole point of this Rp is for that 0.001℅ to survive the destruction of the ship and join with the few other survivors. This way we're all in the same place, alone, with no damn giant army backing us up.

A few* rebels masking as Stormtroopers which manage to first-mess with the hyperspace drive and then second-destroy the ship's systems making it crash??? That's even more idiotic. I mean just think about it, a [b]Super Star Destroyer, one of the largest warships ever designed which also served as a command ships with a crew of at least* 280k, [/b]taken down by a little group of rebel infiltrators???
