Well, there is another way to do it, but you would need a few things.
First, you need a few nukes, ones set up for an EMP effect.
Second, you need to hijack a cargo ship headed for the station.
The plan varies depending on the SOP of the station. If it allows direct connection with the supply DS or requires supplies to be transferred by small craft. The whole thing hinges on the use of the nukes as a standoff weapon. We are looking only for the EMP effect.
You want either the supply DS or the shuttle (depending on the stations SOP) connected before the nukes go off. This pretty much means the shuttle and the supply DS are going to be toasted after. You use the nukes in two (preferably three) waves. This helps make certain that any backup systems are fried by successive EMP effects. You send the nukes in behind the supply ship and timed so that the ship (the DS or shuttle) are connected and people have a moment to start moving around. The nukes, which you want drifting not powered, and can be released early into the DS's initial acceleration, shouldn't be noticed until the last moment and then most probably not recognized for what they are.
Once the EMP weapons go off, you move the true cargo of the supply ships into action. Troops. The whole station should be caught on it's ass. Even if they have an SOP of a yellow alert for supply transfers, it would still be a relaxed one. The station's guards will be disorganized, likely not knowing what is happening, and even some may not be able to access their weapons.
Even if there is protocol for execution of prisoners, they probably won't have time to enact it once, possibly IF, they realize it's necessary. Most of the guards will be fighting or hiding and not worrying about executions.
You need another DS coming in behind the first. This one needs to be FAST. It decelerates and connects to the station with some backup troops and to haul away the prisoners.
Timing: Assuming DS connection to the station. If it's a shuttle, the EMP nukes need to be released earlier and of course the extra step of the shuttle going to the station.
1) Out of system; Seizure of Supply JS and DS.
2) Jump into system; broadcast codes acquired from old crew.
3) Release DS for "supply".
4) At the appropriate time, early in the acceleration, the DS releases the nukes to drift towards the station.
5) End acceleration and begin deceleration phase.
6) Connection to station. "Supply crew" begins talking to station crew regarding transfer of supplies.
7) First EMP weapons detonate. Station loses power momentarily until backup systems start. Supply crew uses this moment to get into position to take over supply deck. No weapons shown yet, any movement dismissed as surprise.
8) Second EMP weapons detonate damaging most backup systems. Chances are there are no backups to the backups. Only hard shielded equipment is still operational.
9) Supply crew starts firefight with station crew on supply deck. This is the cue for the troops in the supply ship ship to unload.
10) Second DS running dark emergency decelerates and connects to station. Off load more troops.
11) Take over station, transfer prisoners, and get out of dodge.
As a modification to the above plan, you could have tugs go in along with the second DS. Connect them up to the station and drag it for a bit. You could use the extra time to stay out of the way of the warship or to strip the station of parts to alleviate the cost of the mission.
