Very much the same. So on that note, how about trying something sneakier than bursting in, perhaps we could develop a plan to enter through the garbage vent and drill the wall into the armory?

How many people do we have?
I would prefer two infiltration teams. The first team should be loud and contain a shit load of firepower to take out that Mech as PV suggested. The second should be covert and enter through some access that might possibly not have an optical security sensor. Or, if by chance your garbage vent does have an optical sensor, the overt/loud boarding team should enter 30 - 60 seconds before the covert team, thereby distracting the defenders from our subterfuge.

Before we say who is on what team, we need to know what we have.
