How to cut open a door

As you will recall (from Rome's Revolution), I previously explained how Rome was able to lock herself in her room, much to the consternation of Commander Ursay and the rest of the crew. There was a crisis brewing as Winfall had just disappeared and unfortunately, they had packed up all their equipment. Here is the actual passage:

The door slid open. Rei cut across the Great Room and ran up the West Corridor, to the C-ring and turned to his right. Standing there was Commander Ursay, banging on Rome’s door, shouting at her, stabbing at the stud on her door. Rei could hear Rome’s muffled voice saying “Ni.” Two burly crewmen were coming down the hallway with some nasty looking equipment in their hands.

This was long before I came up with the concept of the PPT Thrower so what was that "nasty looking equipment" ??



I guess in my mind, I was thinking something like a chain-saw or router. But later, after I invented the PPT Thrower, that would be the obvious choice. So let's just pretend that they had an industrial-sized PPT thrower. We'll assume that they used it for construction of Skyler Base and it was big and bulky but it was the best thing they had to cut the door open. OK?
