If you're new, we suggest reading the sticky at http://amagicalplace.wikia.com/wiki/Sticky to get acquainted with the board's subject matter.

Hey /k/. Newbie to gas masks here and I recently picked up a ГП-5 for relatively cheap. I was just wondering what these numbers on the bottom of the canister meant. Also, general gas mask thread.

you don't use aerosol for that
you use a specially-designed seal-testing device or you use amyl acetate (banana oil)

I work at a gas station in Detroit.
The REALLY GHETTO part of Detroit.
Lately the local gangs have been trying to get their recruits to "blood in" ; kill to join
A bunch of prosties have been showing up dead around the area
I'm 18
The gas station owner encourages us to be armed and says we are allowed to carry a gun around if we like

Buy a Glock 19 or 17 in a private sale. Check Armslist and MI Gun Owners marketplace, there are lots of them floating around for $350-$500.

Normally a rifle would be better, but it's a lot faster to draw and fire a handgun than pick up a rifle and do the same.

What would an American invasion of Canada look like.
Non conventional warfare would not seem to be a factor as the conflict would be largely fought with gorilla and insurgency tactics.

A siege on all southern fronts and a surrender. I doubt blood would even need to be shed in the event of occupation, at least as far as soldiers go, canada's army is less than sixty thousand, our navy is a joke, and while our air force is respectable, it pales in comparison to U.S.

The only real chance would be if all able Canadian men rose up in arms and the death toll amongst Americans became so high that they bombed it to shit, but even then, foreign powers would get involved in the snap of a finger, not to mention finding out who the real allies of who are, how amny countries do you think would support America? How many countries do you think would defend Canada?
Anyways, strictly speaking, it'd be a no contest for America, but we count in variables such as outside influence, America loses in the end.
>>
If the American invasions aim was to secure resources. Canadians could set the tar sands on fire creating an environmental disaster affecting the Americans air and water. Forrest fires could be set along the border causing a brief diversion allowing Canadian kill teams and saboteurs to sneak in.

>exterminate

Lol no.


America would occupy Canada for its infrastructure and natural resources, destroy it would end up being a net loss for both parties, and it isn't that hard for a nation to sabotage its own resources acquiring systems in defense of occupation.


Canada is and always will be MUCH more useful to America as an ally, even in times of war. In case you didn't know, Canadian Special Forces Regiment has the highest kill count of Taliban officers over any other special forces regiment.

New to /k/ and guns in general.
I'm looking for a compact handgun under $400 for home defense.
What would you guys recommend?
>>
you don't buy a compact handgun for home defense you get a compact for carry. You get a shotgun or an AR for home defense. If you need a handgun for home defense get a full sized gun.

if you need a gun for both HD and carry then get a mid sized pistol. Glock 19, S&W M&P Compact 2.0, or CZ P-10 are your current options. Don't go smaller than that for HD,

Anyone here play WWIIOL/Battleground Europe?

Def a great game. It's been around for a decade and a half and it's still going strong. Been playing for almost a decade myself off and on.

wish there were more FPSMMOs out there like it

Yeah, no shame in that. It has an absolutely punishing learning curve. I forced myself to keep playing 10v10 tacticals to learn the mechanics. Eventually I broke through and I'm absolutely addicted now.

I think part of what makes it so difficult is how "realistic" it is- oh, you left the side armor of your 170-point Leo 2A5 exposed to a 25-point Konkurs-M team for a few seconds? Deleted. Forgot to use mortars to smoke off said Leo 2A5 while dueling another superheavy? Deleted by MiG-27K. Forgot to keep your infantry in front of said Leo 2A5 while advancing through forest? Deleted by a RPG-29 shot to the side.

Learning to bind key units to the number keys, and learning the vital hotkeys is essential. You simply cannot become a competitive player until making that jump.
>>
>>36176635

This desu, it's why I prefer single player games these days even. Jagged Alliance 2 v1.13 has its learning curve but I can tackle it at my own pace rather than have to endure realtime multiplayer.

I'm sad that games like it don't get made anymore.

>>36176635
Honestly im a brainlet when it comes to RTS with a bit of realism to it. I got company of heros 2 for free and i get my ass kicked on campaign on easy.
>>
>>36177425
>>36177368
this is why I play games like Total War. there's still realism and history to the series, but because the nature of warfare in older periods of history, the gameplay is less punishing.
>>
>>36177438
Even some games like those can be hard as fuck. Stronghold crusader can be extremely difficult and unless your a master tactitian you arent completing the campaign on anything above easy.

I can never find any solid data on this. This is the closest I can find, but maybe someone here knows?

Also general Abrams appreciation thread.

As good as any MBT in the ~60 ton category. Suberb frontal armor, but pretty much anything can take it out from the sides or the rear. So don't get flanked.

All this doesn't mean that it cannot go through large amounts of steel, however. The 3BM-15 is certified to penetrate 150mm RHA at 60 degrees. The photo below shows the result of the shell penetrating a 200mm steel block (of unknown hardness) at 0 degrees, entering from the top and exiting from the bottom, leaving very large holes on either end. The 3BM-15 clearly outmatched all NATO armour at the time, which could not stand up to it even in the thickest places.

The photo below shows the result of a steel block meeting a BM-15 projectile on a perpendicular impact at an unknown range. steel body disintegrated inside the armour as it entered, but the tungsten slug passed onwards leaving a very clean tunnel (indicating that it still had plenty of momentum).

...fuck...

In the event of a penetration whereby the steel body has not peeled off fully, it functions to blast the interior of the target tank with hundreds of large pieces of steel - absolutely devastating to interior equipment and crew members alike. Thus, while the 3BM-15 was lethal to all NATO tanks of the time, it was exceptionally lethal to tanks like the AMX-30 and Leopard 1, which had particularly thin armour. However, this shell became essentially useless against new NATO armour emerging in the early 80's, like the Leopard 2 and the M1 Abrams, as these new generation tanks had thick steel or composite sideskirts designed to expend the steel projectile. The tungsten carbide slug could not be stopped so easily, of course, but a small slug could do only a fraction of the damage that the full package would have done.

3BM-15 uses the same steel "ring" type sabot as the 3BM-9. The photo below is from a Rheinmetall brochure on PELE ammunition, demonstrating a modified 3BM-15 PELE round in flight and the airflow around the components of the round. The sabot was unmodified.

...right...

An incremental propellant charge is wrapped around the projectile body.


Mass of Incremental Charge: 4.86kg
Maximum Chamber Pressure: 4440 bar

Muzzle velocity: 1785 m/s

Steel body maximum diameter: 44mm
Steel body minimum diameter: 30mm
Armour piercing cap diameter: 20mm
Core diameter: 20mm

Length of projectile only: 435mm
Length of armour piercing cap: 20mm

The steel "wedge" in front of the tungsten carbide slug is an armour piercing cap to protect it from shattering the instant it impacts the target, and to improve performance on highly sloped armour.

I don't say "about .30", but that those fall into the same general class of calibers: those used as general issue infantry rifle and machine gun cartridge.

Now it's of course true that those aren't directly comparable at all in ballistics, power leve, etc.,

Guys I find it really disturbing that Ash apparently has some kind of access to an AR.

Why don't small arms projectiles have wings to generate lift and stop bullet drop? Yes I'm aware they rotate extremely quickly from rifling, but couldn't some mathematical genius figure out some kind of geometrical solution?
