"Greetings, soldier! I am him indeed..." He reaches out & takes the plastic pad, reads. "So you claim you're... good" He shakes his head - "... well, I've seen many claiming this. Fortunately though... I... don't think we'll be dropping you into true combat for a while. Maybe... you'll survive for a while."
He then disappears into some back room, and shows up with a heavy metal case, which he slams down on the table. He opens it: it contains something that looks like the combination of a firearm and some electrical circuits; the case also contains some round metal objects, about the size of a grenade, which do appear to fit into an opening on the gun.
"Rule number one: this is your blaster rifle. You do not give your blaster rifle to anyone, unless you're ordered so by your superior."
"Number two. You do not fire your blaster rifle, unless you're ordered so by your superior."
"Also... until you go through Basic Training, you do. not. open. this case, unless ordered so by your superior.
Also, your superior is... well, me personally, unless we find... someone else unfortunate enough to have to keep care of you. Understood?"
