I was in India during those pesky bomb testings back in 1998.   At that time they didn't have long range capacity.  Sounds kind dumb to shoot a 10 megaton 200 miles.  Maybe they have it figured out now?

In the second world war aircraft carries were limited on air defense in comparison to toady's naval carriers. There would be two lines of defense on a carrier of world war two. The first line was the fighter cap usually posted close to the carrier and then vectored in by the ships radar. If a Japanese plane got through the fighter cap the ship was limited to its anti aircraft guns. These would be of various caliber mounted on several locations on the ship. Americans had some of the best anti aircraft ammunition of the war, as they were the first to invent the proximity fuse on larger caliber rounds. The way anti aircraft fire worked before the advent of proximity fuses was they had a timing fuse on the shell they had to pre-set the shell to explode at a specific altitude before firing it. The proximity fuse had a fuse that detonated the shell close to large metallic objects. The use of missiles for downing aircraft was pioneered in world war two by the Germans using rockets and radio controlled devices. To my knowledge they never shot down a plane with this technology mainly due to the fact like all of the German wonder weapons it was to little to late, thankfully.

Good evening Major,I'm a retired Sergeant in the U.S. Army, possibly at the same time as yourself,oh well.Man, our Country's have really put us lifers through some stuff HUH?

I dont think they were actuall M203's, they were a smaller diameter and I think they were available with a chalk type and maybe a smoke projectile.  Did find a 37mm flare launcher\nhttp://lgweaponry.com/ad_sheets/37mm.htm

Some Googling says that a 9mm bullet weighs about 8 grams (convenient!) and has a muzzle velocity of about 360 m/s.

the answer is in the army files of every nation that ever had a war.\nmachine guns spit out bullets very fast. Or I suspect the old Tommy gun in the 20s' was the one. Gangsters perhaps in Chicago.\n\ngl

Bound's hubby here:\n\nAnd people say creative writing is dead!\n\nFirst ... the .38 Special, .357 Magnum, and 9mm handguns and their respective ammunition are referred to as medium bores. \n\nThe .38 Special, being the oldest, was one of the first "true" medium bore smokeless powder cartridges. While the bullets fired from a .38 Special or .357 Magnum are typically .357 to .358 inches in diameter (9mm being .355 inches in diameter), the inside diameter of the barrel at the grooves is smaller in diameter, and the inside diameter at the lands (rifling) is even smaller in diameter ... this is necessary for the bullet to "fill" the lands and grooves to establish rotation of the bullet in order to achieve any degree of accuracy. \n\nThe earlier blackpowder medium bore cartridge was the .38-40 ... whose bullet was actually .40 cal. (firing a bullet .400 inches in diameter). \n\nThe other "medium bore" handgun prior to this was the .36 Navy, a cap and ball revolver that fired a bullet .351 inches in diameter. \n\nWith the exception of the .357 Magnum, none of the medium bores' names truely reflect the actual diameter of the bullet fired. The reason the .38 Special was named the .38 Special by Smith & Wesson (its developer) was to avoid identification with the .36 Navy ... which WAS a proprietary development of its competitor, "Colt". Performance-wise, the .38 Special was a significant improvement in reliability, performance, and accuracy over the .36 Navy ... and needless to say more modern ... S&W sought a unique identity for its first centerfire medium bore smokeless cartridge.\n\nAs an aside, with the exception of the .22, the .25 ACP, .357 Magnum, the .40 S&W, the .41 Magnum, and the vast variety of .45s, no handgun cartridge name truly reflects the actual diameter of the bullet. The 32 family = .312", the .38 family = .357, the .38-40 = .400", and the .44 family (even the mighty .44 Magnum) = .429".\n\nGood luck!

try www.wildimports.com   They have what you are looking for.  They cost a few bucks, but are actually quite good prices for the quality you are getting.  I LOVE cannons!  Get one!  Try the mountain howizter.....\n\nIf you don't want to spend quite that much money, you can always find a Coehorn mortar.  They make them in golf ball size or beer can size.  Put a charge of black powder in one of those babies and it'll rattle the mountainside!  They are fun too and you can get a decent quality mortar for a few hundred bucks.

The lead sergeant of a platoon the uses mortars. Sounds simple but it was typically, in the Army, a Sargent First Class (E-7). He was the number 2 in command behind the platoon leader (usually a O2).\n\nMortars come in a variety of sizes, are used for up close attacks i.e. between grenades and artillery range.

At that time, the most reliable and accurate rifles were the bolt action where a shell was brought up out of a magazine incorporated inside the rifle. There were many different types of rifles used by the Germans as well as the Brit ts, Canadians and yes even the USA when they entered the fight. The USA used the Springfield 1903-A3; a very reliable and stout piece of equipment. During the war the M-1 was introduced. It was a semi-automatic rifle. It was used all through Korea as well. The bolt action rifle even today is far more rugged and reliable than even the M-16 which gave the military fits for jambing in Viet Nam at first.

Firing at a target that is immediately in front of the weapon.  Ranges are usually measured in yards, for example 3.5yd = "three point five yards".  When you fire so close that it is immeasurable, it is 0.0yd.  People dropped the first "zero", and slang made the second zero read as "blank", so 0.0yd became "point blank" range.

The second set of numbers represents the length of the brass in millimeters. A 7x ("x" reads "by") 57 means that the case, just like an 8x57 is just that, 57mm long. While strange by US standards, try explaining the meaning of 7-08Rem or 7-30Waters to those on the east side of the pond. I also have and love my 7x57. Very mild, but shoots good and flat out a lot further than I can see. My neighbor has a Mauser in 7x64. Wonderful round! Finding ammo is a bit problematic though. He forms his brass from .270Win Seems to work for him.

A mortar is a muzzle-loading artillery piece that fires indirect shells (bombs in the United Kingdom) at low velocities, short ranges, and high-arcing ballistic trajectories, typically with a barrel length less than 15 times its caliber. These attributes contrast with the mortar's larger siblings, rifled howitzers and field guns, which fire at higher velocities, longer ranges, and flatter arcs. Typically a modern mortar consists of a tube into which is dropped a mortar shell (bomb) onto a firing pin resulting in the detonation of the propellant and the firing of the shell.\n\nIn the 19th and early 20th centuries very heavy immobile siege mortars were used, of up to one metre calibre.\n\nA mortar can also be a launcher for fireworks, a hand-held or vehicle-mounted projector for smoke shells or flares, or a large grenade launcher.\n\nMortars are relatively simple and easy to operate artillery pieces. Light and medium mortars are man-portable, and are usually used by infantry organizations. The chief advantage a mortar section has over an artillery battery is its small size and its mobility. It is able to fire from the protection of a trench or defilade. In these aspects the mortar is an excellent infantry support weapon, as it can travel over any terrain and is not burdened by the logistical support needed for artillery.\n\nThere are also heavy mortars of 120 mm to 240 mm calibre. These are usually towed or vehicle-mounted weapons, sometimes breech-loaded, and normally employed by artillery units attached to battalion through division level. Even at this large size, mortars are simpler and less expensive than comparable howitzers or field guns.\n\nA mortar can be carried by one or more people (larger mortars can be broken down into components), or transported in a vehicle. An infantry mortar can usually also be mounted and fired from a mortar-carrier; a purpose-built armoured vehicle with a large roof hatch. A heavy mortar can be mounted on a towed carriage, or permanently vehicle-mounted as a self-propelled mortar.\n\nA round would be a shell.
