I frown at the shotgunner. "Close range weaponry and combat is a very bad idea. The only time someone has survived within 20 feet of an alien was because it was either dead, or was in the process of killing itself before being captured. They react very fast, and would probably be able to dodge your shotgun. We are trying to kill them before we have to get into battle with our tools. Xeno, bring up HMIU One, 'Shredder' Light Assault Rifle, and HMIU Heavy Assault Weapons."
In place of the 3 holograms, 3 different ones appear. These were human, instead of alien. The right hologram had turned into a real-scale assault rifle, with a long barrel, a short stock, a laser-pointer, flashlight, and grenade-launcher underhang. The magizine was a drum mag, and overall, was sleek and deadly.
The left hologram was that of a HMIU: Heavy Mechanized Infantry Unit. The diagram labelled the height to about 12 feet tall, while it had been scaled down to be human-sized. Again, it was very sleek, and was made to move quickly and protect the user very well. There was a chaingun attached to both arms, in place of the hands, with claw-like pieces sticking out of the end of the barrel, presumably to assist the wearer in smashing something, or to keep the user from falling down without damaging the weapon.
The middle hologram was of a very, very big knife for the HMIU, a very large rifle that looked semi-automatic, and is labelled as such, and has something that will get someone a high reaction: a large, short, bulky weapon with a long barrel, and a small clip. A really big oversized shotgun. Labelled with an the effective range to be 50 meters.
"We all go in in HMIU. I'll give you detailed lessons later. Questions?"
