Why would the high brass want to switch to a harder hitting round?
Maybe they foresee fighting China and/or Russia in the future and our potential enemies have created body armor counters to 5.56.
Also maybe the Army has better .30 cal rounds in development and have not released the info.

Correct on both counts.

Quoted:
I've also learned that armies adjust to the weapons they have. If they have less rounds, they will fire less rounds in suppressive roles. They will aim more if they have to.
I agree that adjustments are likely, especially in logistics. At least, if the leadership wants to keep soldiers from going black on ammo during engagements.

But, I'm not so sure that the troops will fire less and aim more, just because their ammo load is halved. Note the similar firing rates in the below examples:

I use to have both, but settled on 5.56 with a .308 bolt gun.  I like the .308 because where I live is a lot of open country, but I realize I'll never be shooting at people 500 yards plus.  It will probably be like 5ft and under if I ever have to.

I was in Infantry from around 1999 to 2005. I don't know if they have changed training or tactics since then. At the time, we had excellent cadre that trained us in the use of 60MM mortars as the platoon leaders "hip pocket artillery". It made a lot of sense to use each weapon system to it's maximum effectiveness. In practice, for whatever reason when I deployed overseas, we rarely used our mortars. We would routinely be disrupted in urban areas of Baghdad by one or two guys with a rifle less than 200 yards away.

A quickly deployed mortar or M203 grenade launcher would have eliminated that threat. But in practice, my particular brigade rarely used these items. We didn't even carry them with us on patrol. My thoughts are that out to 200 yards, use your rifles. Beyond that, a grenade launcher or 60mm is a better tool. With moderate training, when I had an M203, it was routine to put a grenade through a window at 200 yards, which would have been ideal in the outskirts of Baghdad. Perhaps other units used their weapons differently, but we did not. Being fairly fresh out of training, I did not understand why we did not better utilize some of the tools we had access too.

Overall, we did ok though. Possibly our fires were limited due to the highly populated urban environment, and instead we used what we were most familiar with - rifles and LMG's. Having been trained as a grenadier for a bit though, there were a number of times when our rifles were not effective, but one or two M203's would have done the trick.

For most of the "outrange/overmatch/they'retoofarawayformetohitwithmyM4" issues, 60mm is the right answer. Get a lighter-weight 60mm and issue more of them.

Training/tactics issue, maybe? Though it sounds like you did a lot of urban fighting, and the 40mm is probably better than the 60mm for that. 

The thing I really like about the 60mm (from a theoretical standpoint, as I'm as civilian as civilian gets) is the fact you can shoot from behind cover. If the enemy has only direct-fire weapons you could take them out without really exposing yourself, beyond the spotter who can be sneaky since he isn't sending fire downrange to give himself away.

Also realize we have not fought a modern army in a long time. It is bold to assume we will always have air superiority in the next war. Calling in for an air strike is meaningless if we don't control the air and the enemy is hitting you with rounds and your 5.56 can't hit them back.

I've also learned that armies adjust to the weapons they have. If they have less rounds, they will fire less rounds in suppressive roles. They will aim more if they have to.

If Russian artillery is within range, your 5.56 or 7.62 won't matter.

If your enemy has body armor to stop 5.56 then only 7.62 will matter.

240 rounds 5.56 won't matter if it will not go through armor.

Oh damn, somebody beat me to posting iMortar in a "need moar infantry rifle power!" thread.  I'm slipping.  

Seriously, systems like this are the answer to the "overmatch problem".  You standardize Mk18 to be light and handy (>6 pounds with Aimpoint T-1 should be very doable), and you push them to your squad grenadiers (and a few other squad/platoon positions too,  it that's a whole 'nother thread).  You use that weight/bulk savings to get stuff like iMortar, M320, and Carl Gustav out with the rifle platoons where they can squash the shit out of PKMs and the like.

Fight "big guns" with bigger guns, not by trying to make your little guns offer bigger performance less often.

As former infantry, I find that perfectly respectable and see plenty of merit in doing so.  I roll with 7.62 myself and feel no obligation to sway anyone else to do the same.  Caliber wars are stupid.  Proper training supersedes all that shit which, unfortunately,  is generally overlooked. 

Give a high speed, seasoned face shooter an proper M4 and his adversary an Ak, the results will be predictable.  Have the two parties swap weapons and the result will still be the same.

So if the new m855a1 or whatever has a 50% chance of defeating modern body armor (no idea, lets just pretend it's 50%), does that mean a hit on body armor that is stopped is completely ineffective? Would it cause some sort of incapacitation anyway or no? At least enough to suppress them so you can maneuver actual weapons on them?

I mean, artillery is the king of battle for a reason, right?

Yeah, unless you are wearing Master Chief Mjolnir Exosuit, Powered armor. You ain't going to deliberately expose yourself to enemy fire. Unless you are really dumb or crazy. So suppress, fix, maneuver and destroy. Or suppress, fix, hit with IDF or CAS, and destroy.

Velocity and small diameter impact is what will really beat armor. 223 screams out of a barrel, and with a sharp, but hard Point, it'll defeat any armor.

With 308, you have a larger diameter bullet and it's "slow", just 2700 fps. And that's out of a 26" barrel. So when it hits, it has a larger surface contact area. So the energy will dissipate more, because of the bigger contact surface. Just like how the old .45 ACP couldn't penetrate a steel helmet, but 9mm could. So you want to transfer as much speed and energy in as little of a spot as you can.

There is no upside to going to a 7.62 battle rifle. None.

How old is the RUAG AP round? You see, militaries of the world engage in an arms race. Each Army creates a counter to a weapon they will face, so if war breaks out, their weapons system will have an advantage and help them win. If you want to base your argument on an old round, be my guest. I'm sure our brass in the military know the limitations of old ammo. The reason why they are moving up to harder hitting rounds must have a damn good reason. They probably know of an AP round we do not hence why they are using a larger casing.

You can propel an object faster with 45 grains of propellant vs 25.

Maybe they figured a reliable SABOT round? Who knows? Better question is why are they moving up to a round with 2,400 ft/lb^2 of energy vs 1,400 ft/lb^2?

Using double energy can push things faster, retain more energy at distance, simple physics.

The .308 casing is the parent case, relatively speaking more powder = more speed, more options.

Man vs man. Against an advanced army we have not seen since Vietnam. A round that defeats enemy armor is vital to a units success.

Maybe take your anger at the high brass. Ask them why are they changing back to a .308 round? There must be a damn good reason. Unless of course all high brass is stupid?

If only 7.62 defeats your enemy body armor and 5.56 does not then it will matter.

Grunt: "Sir, our rounds are not dropping our enemies! It's like m855 against the skinnies!"

CO, "Shoot them in the face then soldier!"

Grunt, "That's a small target, Sir!"

CO, "General discussion in ARFCOM said 5.56 vs 7.62 does not matter!"


Unit is over run.
Body armor covers a small percentage of a body anyway.

You should let us know from your vast experience in combat.

Oh my.

Apparently Level IV armor makes one a Space Marine, or something. That's good to know.

I didn't tell the military we're switching to 7.62. Higher ups did. Why are they? That should be your focus.

The answer to that is not monolithic.

A friend encountered Chechens with body armor. He's still here. They're all gone.

Also, I was trained to aim at the feet.

So if the new m855a1 or whatever has a 50% chance of defeating modern body armor (no idea, lets just pretend it's 50%), does that mean a hit on body armor that is stopped is completely ineffective? Would it cause some sort of incapacitation anyway or no? At least enough to suppress them so you can maneuver actual weapons on them?

I mean, artillery is the king of battle for a reason, right?

So we keep current ammo and aim for non armor areas? Let's just stop R&D now?

I'm not going to have GPMGs or 40mm? I won't have 60mm mortars? Or a GC? What did I leave organic equipment in the fucking arms room?

As an interim I would move 7.62 with M993 into the squad...on belts.

Yeah, unless you are wearing Master Chief Mjolnir Exosuit, Powered armor. You ain't going to deliberately expose yourself to enemy fire. Unless you are really dumb or crazy. So suppress, fix, maneuver and destroy. Or suppress, fix, hit with IDF or CAS, and destroy.

Velocity ty and small diameter impact is what will really beat armor. 223 screams out of a barrel, and with a sharp, but hard Point, it'll defeat any armor.

With 308, you have a larger diameter bullet and it's "slow", just 2700 fps. And that's out of a 26" barrel. So when it hits, it has a larger surface contact area. So the energy will dissipate more, because of the bigger contact surface. Just like how the old .45 ACP couldn't penetrate a steel helmet, but 9mm could. So you want to transfer as much speed and energy in as little of a spot as you can.

There is no upside to goi g to a 7.62 battle rifle. None.
Stop using logic sir.

But muh 7.62 knock down purr!
What the velocity of m80a1 again?


I'll wait....

If we spend money issuing mortars, CGs, and other HE propelling weapons to each squad, it's a pretty safe assumption that you will, indeed, have them in a firefight. And you can do that without adopting a retarded rifle that cuts your ability to suppress the enemy in half. I mean, if we're going to go by your logic, why assume we will have rifles in combat? We need training on halberd fighting ASAP!

But, as I said before, military acquisitions isn't here to give the military better tools for fighting war.

Does the mil teach to aim for the head or chest?

With that response, I'm guessing chest?

So we should or should not develop a round that will defeat a modern army's body armor since most hits are not in the chest area?

Why did the mil move away from m855 again and R&D'd mk 262, mk 318 SOST etc???

Did the Chechens have modern front line state of he art body armor?

Why is our higher ups switching to .308?

Did our SF engage enemies lately with armor that prevented a pass through?

Why the change? There must be a good reason why upping a caliber for soldiers is more important than ammo weight.

After all, if something works you keep it until it no longer works, right?
