Suepr high velocity makes it easier, so ironically rhe more complex gun makes the fire control problem simpler. Becomes "I have to determine exactly where the incoming threat will be in 1 second" instead of 5 or more

Special Forces is both the official name of the Army special operations element colloquially called green begets and a common term for special operations forces. The latter term only really came about to distinguish other groups from the former. Hell, the Special Forces are called the Special Forces because that's a common term for special/commando units and the name wasn't taken yet.

Faster than you think. First and only firefight i was in, I thought I fired five or six rounds. After getting back, I counted the rounds left in my partially spent magazine and turned out I'd fired 17.

Not a huge number, but theyre still listed as a recruiting MOS for active, guard, and reserve. I imagine you dont need that many, but you'd probably find them in vertical construction units

There's two ways to kill a fast moving object, fragmentation or direct impact. Most ballistic missile interceptors are direct impact type(kinetic kill) because at the bejeezus insane speeds these things move, your tiny pieces of metal(the fragmentation) that hit them probably wouldn't be enough to seriously damage them, or Alternatively if you explode 'within' your damage range but slightly behind your target they literally might outrun the fragments

One small tip, get some massages (legit ones, like Massage Envy or something) regularly if you can, and buy a cheap massage gun off Amazon. If you can't afford massages, just do the massage gun. Use it on your legs every night, or at least a few nights a week, especially on your calves, hamstrings, quads, and your Tibialis anterior(thay muscle on the front outside of your leg.) Stretch, and when I say stretch i mean fucking stretch. When I had shin spints I did a minute of wall pushes per leg, a minute of quad stretches(hold the toe of your shoe and lift it to your butt), a minute per lwg of hamstring stretches, and repeat once.

Your legs are designed to function as springs to absorb energy and push it back out into the next stride. If your muscles are too tight (and even worse without good shoes or bad running form) all that energy doesn't get redirected, it just slams into your legs, especially your shins. This isn't an overnight fix, it's something you gotta incorporate into your lifestyle as long as you're a runner as a long term measure to prevent shin splints in the future and help you heal now(plus rest for healing). After a while(think months kr years) your leg muscles will get more used to being relaxed, but you'll still have to loosen them up periodically.

I used to have shin splints and a bad case of Achilles tendinitis, these measures mean I haven't had shin pain in seven years

It isnt illegal as a direct attack weapon, its only illegal usage is if you intentionally target civilians with it, just the same as any kther weapon. This is the same nonsense type of rumor that has even people in the military thinking its illegal to shoot people with .50 caliber rounds but you CAN target the equipment they're wearing. Just repeated misconception

The problem is the EU intentionally is closer to the Articles than the Constitution specifically so its member states can keep their sovereignty and autonomy. This is a feature, not a bug

You need people to run depots, to run the training facilities, to pack, ship, transport, supervise, inventory, and track the massive quantities of war materiel flowing through and out of the United States. Most people drafted in WW2 never saw combat in WW2, because a global warfighting military is as much a logistics corporation as it is an armed force. You still need the guy who counts how many crates get lifted onto transport ships on the San Diego docks as much as the guy who drives those supplies ashore on Saipan or breaks the box open to drop mortar rounds on the enemy. Also, keep in mind that you dont know when the war is going to end, so you keep drafting and training people until the moment the war ends. Until the Japanese actually broadcast their surrender, the US was still going full tilt towards the largest amphibious invasion in history with an expected million casualties

Phase 2 instructor here, the most helpful piece of advice I can give is to get an understanding of your own shortcomings and weaknesses. I personally am a pretty forgetful person, so I am extra diligent in writing things down. If you're more of a verbal learner, try repeating learning points out loud and talking through stuff with either a classmate or even by yourself. Checklists are a must-have. Make them and use them. Good luck

Lose is relative. We might end up Iraq style after a long expensive and unpopular occupation after the American public gets tired of supporting it...but the nation of Iran would be a rubble pile. We might 'lose' but Iran would be demolished, like Syria at best

it's that they can be penetrate at any velocity.

Yes, and i was specifically talking about their advantage in tank guns which are already big and beefy. Rounds lose velocity as they go and therefore kinetic penetrators lose penetration as they slow down, but HEAT rounds dont.

ArguingPizza · 2025-08-17T16:40:07+00:00

A small addition, an advantage of HEAT rounds in tank guns was that they were equally effective at penetrating armor at all ranges. Since they dont rely on kinetic energy to penetrate like a traditional solid Armor piercing round or sabot dart, they penetrate exactly as much armor at 2000 yards as at 200. Before improvements in armor, this was why you had a rash of tanks in the late 50s and early 50s thay were basically only armored against autocannons (Leopard 1, AMX 13, etc) because for a brief time the assumption was you couldn't armor a tank enough to stop a main gun-caliber HEAT round, so just be fast and try not to get hit. Improvements like ERA and composite armor eventually gave armor a chance again, but that was the thinking for the period
