The breaching shotgun is a specially modified, pump action shotgun designed to breach locked doors. The weapon fires frangible breaching ammo that is designed to quickly break into very small pieces upon impact. This behavior reduces penetration and increases damage upon impact with hard surfaces. These factors make it ideal for breaking locks on doors without penetrating the door and harming someone on the other side. The toothed extender on barrel allows officers to jam the weapon into the door and ensures the correct distance from the lock for the breaching ammo to be most effective. Its compact design permits officers to carry the weapon on their back, allowing it to be carried in addition to the primary weapon.
(or the obsolete term plastique) is a specialised form of explosive material. It is soft and hand malleable and may have the added benefit of being usable over a wider temperature range than pure explosive. Plastic explosives are especially suited for explosive demolition as they can be easily formed into the best shapes for cutting structural members, and have a high enough velocity of detonation and density for metal cutting work. They are generally not used for ordinary blasting as they tend to be significantly more expensive than other materials that perform just as well in that field. Also, when an explosive is combined with a plasticiser, its power is generally lower than when it is pure.
Technically, the first plastic explosive was Gelignite, invented by Alfred Nobel in 1875, though it was supplied in sticks as per dynamite and could not be moulded into shapes.
The first mouldable plastic explosive was Nobel's Explosive No. 808, also known also as "Nobel 808". It was developed by the British company Nobel Chemicals Ltd before World War II. Nobel 808 had the appearance and physical characteristics of green plasticine and a distinctive smell of almonds. During WW2 it was extensively used by the British Special Operations Executive (SOE) for sabotage missions. It is also the explosive used in early HESH anti-tank shells.
Immediately after World War II a number of new RDX based explosives were developed, including Compositions C, C2, and eventually C3. Together with RDX these incorporated various plasticisers to decrease sensitivity and make the composition plastic.
The origin of the obsolete term plastique dates back to the "Nobel 808" explosive introduced to the U.S. by the British in 1940. The samples of explosive brought to the USA by the Tizard Mission had already been packaged by the SOE ready for dropping to the French Resistance and were therefore labelled in French, as Explosif Plastique. It is still referred to by this name in France, and also by a few Americans. However, most English-speaking users refer to it either by the actual label printed on the packaging (eg C-4 or Semtex) or as plastic explosive.
C3 was effective but proved to be too brittle in cold weather. In the 1960s it was replaced by C-4, also using RDX but with polyisobutylene and di(2-ethylhexyl)sebacate as the binder and plasticizer.
Semtex was also developed in the 1960s by Stanislav Brebera by mixing of RDX with PETN and then adding binders and stabilizers.

SGE 400 Gas Mask
SGE 400 gas mask and a Drager NBC gas filter is one
of our most popular respirator systems and one of the
best available anywhere at any price.
The SGE 400 series masks are the newest design from SGE and have
many features not found on the SGE 150 and earlier SGE 400 models such as:
A.) Lens treated with a special Siloxane chemical & scratch resistant coating
B.) A moisture relief valve is added for enhanced user visibility & comfort
C.) The entire face seal is made from medical grade silicone which has excellent
chemical permeation resistance, provides a superior seal against the face & is
far more comfortable to wear than conventional rubber face seals.
VIDEOSCOPE, FIBERSCOPE & BORESCOPE KITS
Videoscopes, Fiberscopes and Borescopes allow access into areas through much smaller openings that the standard cameras and are popular complements to any system.
Videoscopes, which offer 4-way articulation, provide a much better image than fiberscopes and borescopes, almost always making the best choice. Fiberscopes, which offer either 2-way or 4-way articulation, have the advantage of being usable without a monitor, by viewing the image directly through the eyepiece. Borescopes, which do not articulate, provide either right angle or straight views, making them the best choice for certain situations.
All Videoscope, Fiberscope, and Borescope Kits are compatible with the WalkAbout II™ monitor. All kits include a camera cable, battery powered light source, guide tube and rugged carry case. Fiberscope and Borescope Kits also include a video camera and camera lens adapter. All kits are available with either a color or B&W camera.
UNDER THE DOOR CAMERA
The Zistos line of Under-the-Door Cameras are state-of-the-art cameras that provide video and audio surveillance of rooms with closed, locked or barricaded doors. Two models are available. The Dual View UDC provides an upward view of the back of the door, as well as a view into the room, while the classic Single View UDC provides only a view into the room.
A tiny CCD camera (or in the case of the Dual View UDC, two tiny CCD cameras) with infrared illumination and microphone in the tongue are able to slip under doors with as little as 1/4" clearance. The low light sensitive camera, infrared illumination and frame integrating feature provides a quality image of a room in total darkness. The specialized pole included in the kit allows the camera to be maneuvered while standing to the side of the door, providing for officer safety.
Model 173110 Under-Door Remote Viewing Kit
See into a room before opening the door.
The Under-Door Scope slides under doors in less than a quarter of an inch of space. You can pivot its offset 55° field of view to observe the whole room from the floor up.
The Under-Door Scope features a dedicated C-Mount for video camera attachment and an attachable viewing eyepiece for visual observations.
The kit also includes a Right Angle Viewing Adapter that attaches to the front of the Under-Door Scope, showing you a clear view of the inside surface of the door and any barricades or booby traps that may be present.
See in the dark - from outside a closed door.
The Under-Door scope accommodates accessories that let you see in the dark.
ITI's Night Vision Pocket Scope easily attaches directly to the body of the Under-Door Scope for third-generation imaging. You see the enhanced image directly, with a Visual Eyepiece Adapter, or on a hand-held monitor using an optional video camera system.
An infrared (IR) Emitter is also available to supplement available light and create visual images from scenes too dark to permit normal vision.
