They continue giving you a tour of the bank behind the scenes, telling you about the security system but asking you to understand that they do not want to tell you EVERYTHING about it. They keep it to a vague outline and fail to mention some things entirely.
"Don't want to be telling ALL our secrets, do we?" Kraetz jokes.
They have over one hundred battle droids patroling the bank tirelessly day and night, all armed with blaster rifles. They are led by twenty super battle droids. They have one combat unit that is intended for emergency situations; so far it has not seen use.
They have the hi-tech camera droids, one or more in every room. As mentioned, they possess limited intelligence and have a variety of ways of seeing.
They have an alarm that can be activated by personnel or by a trip method, but they leave the means of tripping said alarm unmentioned.
They also have force field traps that detain would-be robbers. They also leave out how to activate this one as well.
They mention that there are more systems at work. And in control of it all, Kraetz, who proudly carries a blaster on his hip and keeps everything operating smoothly. Obviously he cannot work all day like the droids, but they do not tell you what is done when he is not in.
