Section 1: Awaiting Assignment
While waiting to be assigned to a squad by a Logistics Officer, you are not to push or shove the marine in front of you. Doing so may cause you to be faced with disciplinary measures by your friendly neighborhood MP. Remember, the more orderly the line is, the faster it'll move. Be patient, you're a trained soldier, not some hippie from the National Guard. If by any chance there are no Logistics Officers around, you are to politely request one to come to the assignment area via the radio that every new recruit has been given. Even if one doesn't arrive, the last thing you want is to cause a scene, you may simply have to find one yourself and ask personally.
Section 2: Equipment and Firefight Discipline
We in the Corps have a wide variety of weaponry in order to protect the interests of the United Americas and her holdings. However, the most common weapon amongst the Colonial Marines is without a doubt the M41A Pulse Rifle, which is capable of holding up to 30 bullets of 10x24 mm caseless ammunition. I've yet to see any other weapon truly outshine this wonderful creation, but that can always change.
You are to wear the standard uniform at all times after being assigned to a squad, you better take those pyjamas off after you get out of cryo sleep, this isn't a sleepover. For emergencies, every marine is issued a flare, a Tramadol painkiller pill, a breath mask and oxygen tank, and a crowbar. It's highly recommended you keep all of these items, as many of the areas we enter are often not well-lit and may be depressurized. The flares burn out rather quickly, so it's recommended you bring more than one. Your marine combat boots have a sheath capable of holding a combat knife. It's always a smart idea to keep one there, in the chance that you happen to get captured. After all, what kind of weirdo takes off a man's shoes? You can also affix a knife to your rifle like a bayonet. This is a very good idea, as you may have to enter close quarters combat as a last resort. The bayonet can also be used to break through glass and other weak solids.

This is going to be your best friend from now on. Kiss your left hand good night.
When in a firefight, you are NOT to panic. We issue you body armor for a reason, soldier! You are to remain level headed and open to changing tactics at any time. After all, an adaptive force is an unbreakable force. If you are injured or incapacitated during a conflict, you are to step away from the front-line if able, or hopefully have one of your fellow squad mates bail you out, it's why we've assigned you them after all. Speaking of that...
Section 3: Squad Composition and Chain of Command
When in a squad, you are to always obey the requests of your squad leader, or if by some insane mistake, you ARE the squad leader, you are to report all of your findings and battlefield updates directly to the commander via the command headset you are issued. Remember that the commander has the final say in all matters on the ship and on any missions you may undertake. Disobeying the orders of the commander may lead to incarceration under Marine Law, so you had best watch yourself.
Now for the squads themselves. Ideally, a squad has at least one squad leader, an engineer, a medic, and a few grunts with standard issue equipment. In a foreign environment you may not always be able to access certain areas, which is why an engineer is ABSOLUTELY essential to your squad. Your squad leader is the only person who is issued a motion tracker and grenades, so he is also a VIP that should not be squandered lightly. The medic is the only person in the squad who can potentially prevent a fatal injury on the battlefield. Sure, every marine has a painkiller pill and some bandages issued to them, but they will surely run out and the effects of the painkillers do not last forever. So, unless you want to be taken home to the Sulaco in a body bag, bring a medic with you.
Section 4: Transportation Operating Procedures
In the Colonial Marine Corps, we have a wide variety of ways of entering space stations and planets. Unfortunately...the Sulaco has had some budget cuts recently so all we have at the moment are two transport shuttles. You are not to leave the Sulaco via these transports UNDER ANY CIRCUMSTANCES without verifying the nature of the operation first. What this means, maggot, is that you better ask your squad leader or commander what the hell is going on before you take a joy ride. On the shuttles you are to buckle yourself in your seat and await confirmation from your superiors before lifting off.
