Bouncing betty how does it work

A highly effective tactic in the four outlying huts is to plant one mine at or behind the entrance, and have a machine gunner stand on it. The player will dispatch most zombies, and if a stray one gets too close which normally happens while they are reloading , it will get killed by the mine.

A mine should also be planted at each window, far enough away that they will not detonate while the zombies are outside, but close enough to act as a fail-safe if one gets through. In Der Riese the player can buy Bouncing Betties by the Juggernog machine for points and they get two per round. A good strategy is to leave a crawler and put Betties by the window and stairs above the Bowie Knife as lots of players camp there to make a mine field.

If the player has only one Betty and a Max Ammo is collected, the player will get another one. This is particularly useful during dog rounds, allowing the player to quickly rebuild their defenses providing they are used before the next round begins.

Note that this does not work if both of the player's Betties have been used. In Call of Duty: Modern Warfare 2 , Bouncing Betties only make a single appearance in the campaign level " Loose Ends ", when the player walks into a minefield and is ambushed by Makarov 's Ultranationalists.

To avoid being killed by the mines, one must quickly go prone to dodge the explosion. They cost, function, and look just like their World at War counterparts. However, in third person, the placing animation is similar to placing claymores. The Bouncing Betty gets increases in damage every round. They are useful for covering back entrances to positions, making it much easier for a player to defend a location. The Bouncing Betty is thrown, and will flash a green light for teammates, or red for enemies.

Unlike Claymores , the Bouncing Betty explodes degrees. Also, Bouncing Betties are much more discreet and harder to spot than Claymores, as the flashing lights on them are arguably less noticeable than the two bright red lasers protruding from a Claymore. However, these advantages are counterbalanced by the fact that Bouncing Betties have a much smaller kill radius than their Claymore counter-part and take much more time to detonate, as the Betties need to bounce in the air before exploding.

This gives ample time for opponents to avoid it by cutting a corner and is rendered near useless against Stalker Pro users as they walk by. Players can also avoid a triggered Bouncing Betty by quickly going prone, avoiding the explosion in the process.

The player can also crouch but will get badly hurt; in fact, even a very slight elevation will result in the Bouncing Betty killing a crouching player. Players can even completely avoid a Bouncing Betty by simply going prone and crawling past it. Despite the small kill radius, the Bouncing Betty owner can be killed by their own Bouncing Betty if an enemy triggers it and the owner is within its radius.

It functions in the same way as the Bouncing Betty in Modern Warfare 3. However, they are much more potent in Black Ops II , as their detonation time is very quick and their blast radius has been buffed significantly. After the 1. Compared to the claymore, the Bouncing Betty is less reliable for defending doorways and other choke points, but it can be thrown, whereas the claymore must be placed. This makes the Bouncing Betty useful for quick deployment, as well as the ability to throw it over obstacles, making it effective as an explosive trap should the player use it in an offensive manner.

Most tanks and other military vehicles apply that kind of pressure. Let's take a closer look at one of these anti-tank mines. All anti-tank mines are blast mines, because the goal of the anti-tank mine is to destroy the tank's tracks and as much of its body as possible. There's no need for a bounding or fragmentation anti-tank mine. The M15 is a circular, steel anti-tank mine that contains a main charge of TNT. It has a diameter of The main component of the M15 is the The M15 is armed by rotating the arming switch so that it is set atop the head of the fuse.

The cylindrical fuse is made of iron and is attached to the pressure plate by a copper cover. As a tank rolls over the mine, it pushes down on the pressure plate. Underneath the pressure plate is a Belleville spring with a firing pin affixed to its underside. The firing pin is driven down into the detonator, which detonates and fires the M booster charge beneath the fuse, which then sets off the main charge. Landmines can remain active more than 50 years after they are planted in the ground.

For this reason, there is a growing worldwide effort to rid the world of landmines. To do this, we must first locate the millions of landmines that are still buried in dozens of countries around the world. Finding these landmines is extremely difficult, as most minefields are unmarked. And those that are marked can take years to de-mine. Landmine detection is a slow, methodical process due to the danger involved in locating landmines. While location technology is improving, the following conventional techniques are still relied on heavily:.

Scientists at Ohio State University are developing a new ground-penetrating radar GPR device that may be more effective in locating and disarming landmines. This new device would be helpful in locating mines that have little or no metal content. All landmines, including plastic ones, are filled with explosive agents that have electrical properties that make them detectable to the right technology, such as GPR. A GPR device focuses radar energy just below the ground and just a few feet in front of the user, according to researchers.

The device ignores signals that bounce back from the surface and uses specially designed software to make buried objects shine brighter in the radar image. The GPR has been successful in detecting two common landmine casings filled with a waxy substance that is similar to TNT.

Once a landmine is detected, the GPR device shoots two chemical agents into the ground to deactivate it. One agent solidifies the triggering mechanism along with surrounding soil, allowing soldiers to cross the ground. The second chemical agent then solidifies the mine and soil permanently.

The mine can then be shoveled out and destroyed. When there is not a lot of time for an army to clear a minefield, it will often employ the use of certain machines to roll through and clear a safe path.

Military forces employ several kinds of mine-clearing machines to clear out or detonate mines. Some machines are specifically designed for the task of mine clearance, while tanks can also be fitted with certain mine-clearing devices. There are several types of mine-clearing machines. New machines are remote controlled, which minimizes the risk to personnel. Mine-clearing machines use one of three techniques, including flailing chains to beat the ground, rollers to roll over and detonate mines, and rakes or blades to plow through the minefields, pushing the mines to the side.

The S-mine is a type of bounding mine, a specific class of mines that are launched into the air before detonating at a desired height. The S-mine in particular jumped to a height of around 1 meter, where it then exploded a filling of shrapnel to nearby troops. They were built from all the way till the wars end in , with almost 2 million being made in total. The main body of the mine was a steel cylinder 15 cm high and 10 cm wide, and contained a black powder propellant charge at the base to launch the mine.

Around the edges of the container are around steel balls, which are projected out by a central TNT explosive charge. Surrounding the mine was approximately steel balls, scrap metal pieces, or short steel rods.

These pieces would be propelled at high velocity out from the mine. The average time between the triggering of the mine and the propelling charge being set off was 3.

This time would vary based on the condition and age of the mine. The rated lethality range of the mien was 66 feet 20 meters and could inflict casualties out to a distance of feet meters. Unfortunately, due to some bad propaganda that got out in the United States during WW2, there was a myth that spread that if a soldier stepped onto a S mine, it would not go off until stepping off of the trigger.

This was incorrect as the mine trigger did not wait for the pressure to be released before activating the device. If one chose to run or stand still after activating the mine, it would prove equally deadly. This would not necessarily guarantee the mine would not harm you, but would minimize the amount of shrapnel the body would get hit with from the mine.

Since the German S mine was made up of mostly metal components, it was susceptible to being detected by metal detectors in the field. There were not a large number of these devices deployed to Allied infantry units; however, so the alternative method was to probe with a bayonet or knife a low angle in the ground. The probing action had to be accomplished at an angle, or the action would set off the pressure sensor of the mine. Once discovered, he soldier would place a pin into the safety pin hole of the device to prevent it being set off.

If there was an electrical trigger or tripwire affixed to the mine, then the soldier could simply could the wire.
