This could piss someone off...

The military asks for a specific query of people to join, like men from 18-25 or something like that if i recall correctly. Of course, women are able to enroll as well, but with the same age preferences.
I find it a bit strange that the military is mostly men in the most fertile of their lives and highest sex drive. The most likely to reproduce are out in war, and has a higher chance to not come back at all.
With the war ending, we are several healthy, breeding men short of the population. Most men being fathers already, now whose kids have no father, and mother having to care for them on her own. In sense, bastard(ed) children (if the terminology is correct anyway- child without father? Idk) So with these men gone, the generation has a reproductive set-back. In sense is good... Not to be so cold, but the population of humanity, if i remember correctly is 7 billion or so. By a big enough war, could bump it down a million or so. Which means more resources for the rest of the citizens. It's violence, but its still politics. Its considered a legal, humane way of thinning out population and figuring out whatever political issue they have that could be decided by a chess match or flip of a coin.

I don't like the idea of sending anyone to their potential death unless they have wronged humanity in such a way the society would be better off without them. The idea of taking recruits of healthy, able to breed adults of sound mind and then mold them into killing machines, use them for war, and if survived, are thrown back into society like nothing happened. These people are now trained killing machines, with war experience, have seen bloodshed of their allies and enemies. Live rounds whizz past their heads, and they killed- taken fathers away from children, brothers from fathers... In sense, in the name of politics. I mean no disrespect to military personnel, i respect all branches of the armed forces as much as anyone should. They put their lives on the line to defend their country, and their loved ones within it. What is not to be respected of that?!

Instead of taking these sound minds of society and re form them to kill, and drop them into the world after battle; Instead of cursing the kindest people with PTSD; Instead of rendering so many kids as bastards, Why don't we send in the natural-born killers into battle. After all, they already know what its like to kill someone, the sight of blood doesn't bother them, in sense they are already trained to kill, or at least f*** some guys up. The killers in prison. Prisons are crowded right? Well... Send them into war. They are probably on death row already anyway, throwing them in war would be a favor. Some know how to be stealthy so they are like f***in' ninjas... They have been in prison for X number of years, so they can defend themselves with a toothbrush, or thread from a pillow case. VERY resourceful little f***ers. The war would be over before the enemies even knew it started. Right in there cots as they sleep in the night, not a shot fired. Silent attack...
Obviously, there is the issue of how do we get them back in prison AFTER war?
Well, tracking devices can be implanted in them where they cannot remove it themselves. But that isn't fail safe... I'm thinking like in "The Running Man" with Arnold Schwarzenegger. If you haven't seen it, the criminals wore this metal thing around their necks. Looks ridiculous, really. But a perimeter was set up with these poles with sensors on them run by a password-protected security computer. If an inmate passes the armed perimeter his head would be blown right off his shoulders by the thing around their neck. Gruesome bit of tech, but cannot argue with the results... unless you have a couple of smart guys seeing the password like in the movie...
Any way, if it were something similar to that, but with the implants in the back of their heads, say, right where the spine meets the skull. Other personnel keeps a close eye on our inmate infantry, and if they get to civilian area, or out of a certain "out of bounds" place, trigger the device and send the fool an electrical impulse into his nerves and collect the bastard who tried to run and throw him in solitary confinement at the prison for the intent of a war crime.
At some point (most likely at the beginning) the inmates would want something in return, like a full pardon. Hahaa! for a murderer on death row? Please... Your dreaming.
So their would have to be a bribe to get them to cooperate, and it wouldn't have to be a full pardon, but maybe a reduction in sentence, good meals for a short time, privileges most inmates wouldn't get unless they participate in the "Inmate Infantry" program.

Just those thoughts- something to consider, think about. Whatever.
When/if we run out of serial killers and other low-life scumbags in prison to throw into War, then we can send in our personnel to finish what the meat shield couldn't.

With this option, we will make room in prisons, spend less money on training and gear for military, less money spent in prisons, and more of our loved ones making it home to their families.

Or we could just make Marijuana fully legal, and have peace, impotence, and no wars.
ANOTHER way to thin out the population... Right?
