One, titanium is so much lighter than steel you end up with more recoil and therefore less control over a weapon on full auto.
Lighter machine guns are EXACTLY what we need, and it irritates me to no end that we will spend MILLIONS of dollars on one aircraft, but we won't spend the cash to develop a light weight machine gun. Machine guns used for sustained fire (like the 240) and as automatic rifles (249) are generally fired from either bipod or tripod, so recoil management wouldn't be so bad if they were lighter. Individual weapons (M4) are generally used in the semi mode simply because outside of close quarters, automatic fire is a waste of ammo for anything but suppresion...and suppressive fires are best left to our 249's and 240's.
Two, if the government doesn't want to spend 1500 a soldier for current tech body armor, why would it invest 100k+ per soldier in a effective exoskeleton system?
You wouldn't HAVE to equip every soldier with an exoskeleton in order for them to be effective. 3 per rifle platoon would make me happy, and I would put them to good use.
HERE IS THE TRUTH concerning the future of American warfare!!!
"...the next soldiers weapon will be digitized, weigh about 100 lbs (90 of it battery), Microsoft compatible, and will enable the REMFs to turn off the Joe's weapon when the integral camera doesn't show the ROE compatible image
It's a damn shame too...
I was looking through an army times magazine at the barber shop (which, by the way, is a P.O.S. rag I wouldn't use to line a bird cage with) and saw some idiots great idea about a future individual weapon system. It had all kinds of stupid crap you DON'T need and a CAMERA was one of them. Soooo, in the future, if this goes into production, not only will our troops be killed because of ridiculous ROE, but they will also be killed because they know EVERY shot will be reviewed by some sorry arse lawyer which will make them hesitate. Hesitation gets you killed in a fight...
In my opinion, the weapon of the future will not be projectile based, but energy based. This will, in turn, make armor obsolete, which will allow soldiers more freedom of movement until they come up with some other heavy armor to stop the energy based weapons...and the circle will complete itself again.
