"Let's get to it," Viveros said. And with that she raised her Empee, sighted it on some far-distant Consu, and began to fire. We quickly followed.
How to prepare for battle.
First, systems check your MP-35 Infantry Rifle. This is the easy part; MP-35s are self-monitoring and self-repairing, and can, in a pinch, use material from an ammunition block as raw material to fix a malfunction. Just about the only way you can permanently ruin an Empee is to place it in the path of a firing maneuvering thruster. Inasmuch as you're likely to be attached to your weapon at the time, if this is the case, you have other problems to worry about.
Second, put on your war suit. This is the standard self-sealing body-length unitard that covers everything but the face. The unitard is designed to let you forget about your body for the length of the battle. The "fabric" of organized nanobots lets in light for photosynthesis and regulates heat; stand on an arctic floe or a Saharan sand dune and the only difference your body notes is the visual change in scenery. If you somehow manage to sweat, your unitard wicks it away, filters it and stores the water until you can transfer it to a canteen. You can deal with urine this way, too. Defecating in your unitard is generally not recommended.
Get a bullet in your gut (or anywhere else), and the unitard stiffens at the point of impact and transfers the energy across the surface of the suit, rather than allowing the bullet to burrow through. This is massively painful but better than letting a bullet ricochet merrily through your intestines. This only works up to a point, alas, so avoiding enemy fire is still the order of the day.
Add your belt, which includes your combat knife, your multipurpose tool, which is what a Swiss army knife wants to be when it grows up, an impressively collapsible personal shelter, your canteen, a week's worth of energy wafers and three slots for ammo blocks. Smear your face with a nanobot-laden cream that interfaces with your unitard to share environmental information. Switch on your camouflage. Try to find yourself in the mirror.
Third, open a BrainPal channel to the rest of your squad and leave it open until you return to the ship or you die. I thought I was pretty smart to think of this in boot camp, but it turns out to be one of the holiest of unofficial rules during the heat of battle. BrainPal communication means no unclear commands or signals—and no speaking to give away your position. If you hear a CDF soldier during the heat of battle, it's because he is either stupid or screaming because he's been shot.
The only drawback to BrainPal communication is that your BrainPal can also send emotional information if you're not paying attention. This can be distracting if you suddenly feel like you're going to piss yourself in fright, only to realize it's not you who's about to cut loose on the bladder, but your squadmate. It's also something none of your squadmates will ever let you live down.
Link only to your squadmates—try to keep a channel open to your entire platoon and suddenly sixty people are cursing, fighting and dying inside your head. You do not need this.
Finally, forget everything except to follow orders, kill anything that's not human and stay alive. The CDF makes it simple to do this; for the first two years of service, every soldier is infantry, no matter if you were a janitor or surgeon, senator or street bum in your previous life. If you make it through the first two years, then you get the chance to specialize, to earn a permanent Colonial billet instead of wandering from battle to battle, and to fill in the niche and support roles every military body has. But for two years, all you have to do is go where they tell you, stay behind your rifle, and kill and not be killed. It's simple, but simple isn't the same as easy.
It took two shots to bring down a Consu soldier. This was new—none of the intelligence on them mentioned personal shielding. But something was allowing them to take the first hit; it sprawled them on whatever you might consider to be their ass, but they were up again in a matter of seconds. So two shots; one to take them down, and one to keep them down.
Two shots in sequence on the same moving target is not easily accomplished when you're firing across a few hundred meters of very busy battleground. After figuring this one out, I had Asshole create a specialized firing routine that shot two bullets on one trigger pull, the first a hollow tip, and the second with an explosive charge. The specification was relayed to my Empee between shots; one second I was squeezing off single standard-issue rifle ammo, the next I was shooting my Consu killer special.
