Okay, so: 

HeySeuss is going to help me out and handle the opener.

A few things (and HeySeuss can correct me if I'm wrong on anything):

The opener will start DURING a set-up run. 

It'll involve a bit of combat. Nothing too heavy.

The group will already be assembled, doing a run to get their hands on heavy equipment that would be impossible to trace. (Otherwise they could just buy it/have a fixer provide it.) 

Huge thanks to HeySeuss for rescuing me here.
