Devlin, male human Imperial 'soldier'
Scouting is not really Devlin's strong point, so he assumes that Rannick doesn't intend for him to go. Nor is holding the high ground with a rifle either, come to think of it. Marching up to the front and talking his way in is more Devlin's thing. But given that they are probably rebels, the odds of charming them into extending an invitation are slight, and given the thick slab of plassteel, the odds of Intimidating them into doing so are similarly drepressing.
Devlin holds position and considers the options.
"A sweep of the area could be useful. It it shows nothing, then perhaps put two men in covering positions and move up and see what we have, sir."
ooc: of course, this is SW. Fortified bases don't have defensive parimeters and guards. You just walk up and rap politely on the door. At which point a little sentry unit will pop out of the door and interview you.
