The Baron Vladimir Harkonnen wanted his first class to be practical and entertaining, so he had chosen "An Introduction to Muggle Weaponry" as the topic. In order to make the class interesting, he'd decided it would be a hands-on experience, and had negotiated with Basher Tarr to obtain an assortment of Muggle weapons, mainly a quantity of AK-47 assault rifles, along with plenty of ammunition. These had been marked with stenciled letters declaring them "Property of the Muggle Studies Department", and were now stacked up neatly on a table at the front of the room, near some crates bearing the same lettering, and a rocket launcher. A section of the room had been magically expanded, and turned into an indoor firing range, complete with human-shaped targets, and the usual classroom area was equipped with rows of neatly-lined desks.
The Baron remained in a large, comfortable chair at the front of the classroom, his assistant Jasper beside him, and chatted quietly with him about a few details of the lesson plan as he waited for the last students to arrive and seat themselves at the desks. When it seemed that no more were going to appear, he floated up and shut the door with a flick of his wand. The deep, melodic basso of his voice carried easily over the chatter.
"Welcome to Muggle Studies. The subject we'll be covering today is potentially dangerous, so pay attention!"
This declaration was accompanied by one of his disarmingly cherubic smiles. "The first thing that you need to know about Muggles is that even though they often are extremely silly, they are still capable of wreaking havoc and destruction. It's one of their favorite activities, but somehow, they still haven't managed to obliterate themselves. As there are a great deal more of them than there are of us, even though their methods are often crude, in a war of attrition, the wizarding world might have a problem. So, today I am going to familiarize you with some of the most commonly used weapons in current ground warfare."
He gestured at Jasper, who brought him an AK-47, which he held up and explained, "This is one of the most common Muggle weapons, the assault rifle. This model is the AK-47, a basic piece of artillery used by infantry. It was developed in the admirable nation of Russia, from which my own House claims ancient roots, and came into predominance shortly after the conflict known as World War II. It's operation is simple, and its main feature is that of selective firing modes- it can be operated either as semi- or fully automatic. In fully automatic mode, its range is shorter and less accurate, but as it is generally used in close confrontations, it is effective enough. The semi-automatic mode is more effective at a distance. This is not a very advanced weapon, but, it's still killed millions of Muggles." The Baron demonstrated loading a cartridge into the weapon, flicked off the safety, cocked the mechanism, and turned to fire a round through one of the lined-up targets, with perfect aim. He then flipped it to the fully automatic mode, and opened fire again at the same target- the spray of bullets was less accurate, but still shredded the target's torso region. "Magic or no, you don't want to find yourself surrounded by a horde of Muggles with these." He passed the AK-47 back to Jasper, and indicated the nearby boxes, and Jasper brought him a specimen of their contents after replacing the rifle.
"This is an M67 fragmentation grenade." He held up the grenade for the class to see. "This is a common anti-personnel weapon. It's a basic explosive, based upon filling the enemy with lethal bits of shrapnel. It's not a pleasant way to go. These are commonly used in ground combat, as, they are inexpensive to produce and easy to transport. Their effective radius is a mere 15 yards, and its lethal radius even less- but enough of these tossed into oncoming troops can be painful." With a smile, he removed the safety clip, pulled the pin, and tossed the grenade into a corner of the magically expanded area, where it exploded. The magically enlarged area was intentionally big enough that he could do this without maiming the students, although the nearby targets were mangled. "If those were people, they would not be feeling well now. The Muggles have several varieties of grenades, including concussion grenades that work best in enclosed areas, and incendiary grenades, designed to damage structures."
He drifted over to the rocket launcher, which he laid a hand on as he spoke. "And this little beauty is the M47 dragon, a shoulder-mounted rocket launcher. This model is slightly out of date, but effective. This weapon is primarily used against armored vehicles such as the tank, which unfortunately I have not been able to obtain yet. I'd demonstrate it, but, I'd prefer the walls to stay in one piece. However, if you attend the second portion of my class, you may have a chance to try it for yourself, along with the various sorts of grenades."
"Now, each of you will take one of these AK-47s, a cartridge of ammunition, and pair up with a partner. If you have experience with such weaponry, please find a less experienced student to assist. You will load the weapon, and you will attempt to hit one of these targets, while standing behind this line." He indicated a white line stretching in front of the targets. "You will try both modes, and learn the different feel of each one. And, you will not shoot each other with them. At this time." He grinned slightly, as he added, "Part two of the class is optional and will be held at a later date, but I encourage all of you to attend. We will be having a little Muggle-style war game on the grounds, and, you will be welcome to try and shoot each other then." A faint shimmer went up around the Baron as he flicked on his personal shield and settled back into his chair, watching for any that might need assistance. Jasper moved to join the students, ready to offer help as well or remove any troublemakers as needed. He didn't bother with any sort of shield, since getting shot didn't concern him.
