Life on the oncoming lane
You're not in combat, yet. Thanks to Ominous presence's crit on the perception roll, you're ambushing the guards - the fun won't start until you take an offensive action that can be spotted by the bad guys. So it's perfectly reasonable to jam up their comms and then jump them. Remember these are normal, unaugmented humans, so initiative is going to be yours.What kind've action is the tech roll? Can I do that while also executing an attack?
Also, Abigail's gear for this mission is:
A standard Combat weapon - still a PDW, but with plain ol' bullets.
A standard Combat melee weapon - an electrified spike along the back of her hand.
Mythimna Panopoly armor.
Or to be more specific: taking this guys out is a joke for you all. The issue here is not "can you take them out?" but "how do you take them out?". Depending on your method of choice, things can happen, like the aforementioned example of shooting explosives into the room: guys are dead, console is too. Maybe you decide to go hand-to-hand, and one of them has a chance to set the alarm. Or maybe you shoot your way in, guards all die, console survives and you get all the nifty info tucked in there.
