Why do IFV's use necked cartridges?

It doesn't make sense to me. An IFV wants to have a large caliber HE shell for infantry etc. and a sub caliber dart for armored targets.

So why isn't everyone just taking the small 25 mm shell that you can carry a fuckton of and making it straight walled so you can lob heavy big 40 mm grenades with low velocity and still shoot effective darts?

That would be the best of both worlds, good payload, good ammo capacity, and good penetration, and while you're at it, make the case telescoped and out of plastic.

No there's plenty of solutions that can be made to achieve fairly similar performance as the mouse while working in a moving vehicle.
A couple of things, the amount of movement the user can make must be large so that he has more incremental control, this is why FPS players have low mouse sensitivity and large mousepads.
Another thing is the type of movement, currently the aiming devices work like console controllers, where user input corresponds to movement speed in a direction, whereas with a mouse, user input corresponds to movement distance in a direction.

So for example you could have controls that are similar in form to the current one but much wider for more accurate control and also work similarly to a mouse where you have to "lift" the mouse and move it back and forth to make the full circle.

>lack of proper heat dispersal requires active cooling, else a low sustained rate of fire
>square-cube law means that thermal energy is increased by the third factor for a increase of barrel area in contact two times larger
Albeit, we have very good energetics that aren't hygroscopic, and can take a beating. Heat sensitivity will always be lower given the reduced density and properties of propellant, but again that can be accounted for.
Cost is definitely harder to work around without compromise.

Why did russia even adopt a camo made by their rival? The EMR camo was essentially their pet project in modernizing their military and now they are abandoning it for some foreign made camo with a uniform likely made in china. What went wrong with the EMR?

Buying vs consigning anon

I never buy from either of those sites because most of the stuff they have is retail price
But i've had good luck consigning at legacy because i can get retail+ for my guns sold there, which is better than trying to sell myself on my <30 feedback gunbroker account. Once you get into the $1000+ range for selling, you get much fewer bites on GB if you don't take credit card

Before these things, suicide drones had to physically touch the target to damage it.
Now, they can just come into say 200 yards and let rip with a volley of high explosive rockets
It's taken away that last 200 yards of time the ship has to destroy the drone.
That's not insignificant.

What's the ideal height for a soldier? If you're 6'6" for example, there's of lot of positions that you would have trouble fitting inside of, such as pilot cockpits and tank crew positions. So theoretically there's an ideal height to be, that's not too short, and not too tall for the military. What is it?

>>61691153
5'11. Thats what Armored vehicles are made for, that's what most clothes are made for, that's what doors are made for, tall enough to not struggle with rucking and have a decent stride length but not so tall it becomes difficult to put on muscle. While manlets struggle with LOP in rifles where its not adjustable and tall people have to chickenwing uncomfortably, you wear them effortlessly. The world is made for you when your 5'11. I mean you reasoned it out in your post, so you already knew the answer, or at least were in the ballpark of what it is.

Lots of stretching and officers automatically get a +25% health, durability, and appearance buff. It comes with the commission.

You know how lots of M1913 rails these days have a channel down their length to save weight? Somebody should make a revolver with a topstrap/vent rib that has a red dot cut at the very back, and then pic rail all the way out to the muzzle with the lightening channel acting as the rear sight notch for a dot on the inside middle of the frontmost rail slot.
That way the gun comes with fixed sights no worse than revolver people are used to, but it also has provisions for installing modern aiming solutions without any aftermarket involvement.

lol, America lost to Chinese rice Farmers.

what are some good interviews or podcasts where the guest extensively talks about his experiences in the armed forces? both about the training, the institution, and combat.

I'm a Gordon Ryan one with Tom Spooner who's a guy that's been in for 22 years, 10 years delta, and yet in a 4h long podcast he doesnt talk about his combat experiences but about his alcoholism recovery and sbit for the first 2h.

so could you give me some good ones? I watch them as war memoirs, so I dont care about them if it's just a therapy session.

Boo fuckin hoo, darkies will always find a way to bitch about any situation they're in. The Army gave those coons the chance to improve themselves by earning respect from their peers, instead most jigs preferred to rape and pillage our southern allies and were nothing more than a PR nightmare. Then when the fucking spearchuckers get called out fro their niggatry they decide to chimpout and "kill day whities" cause they couldn't handle the stress of fighitng a war were they had combat superiority at almost every stage of the war.

In short, always ignore anything these double dipped liars say, even today they'll join solely to rob the tax payers of their hard earned dollars so they can buy their shitty walmart tvs and "peacefully protest" any time they're foreced to do any real work.
