A recoilless firearm apparatus for firing at least one bullet of a respective standard cartridge, including a front barrel, a disposable firing activator and a rear discharge opening formed behind the front barrel and aligned with the longitudinal axis of the front barrel. The standard cartridge further includes a casing having an external diameter that is smaller than the rear cartridge-chamber diameter, wherein the casing encloses a sealed inner-casing space that contains gunpowder, and wherein the casing includes a primer. Upon activating the primer, the primer explodes to thereby detonate the gunpowder, forming propellant gasses inside the cartridge that are directed both forward and backward as follows: a) forward: firing of the bullet via the front barrel; and b) backward: pushing, by a recoil force F.sub.p, the casing, being a counterweight to the bullet, to thereby eject the casing from the firearm apparatus via the rear discharge opening.

Systems, devices, and methods for determining a predicted impact point of a selected weapon and associated round based on stored ballistic information, provided elevation data, provided azimuth data, and provided position data.

Video sources and inertial sensors are attached to a weapon and to goggles. A computer receives video images from the weapon- and goggles-mounted sources and inertial data from the sensors. The computer calculates a location for an image from the weapon-mounted source within an image from the goggles-mounted source using the inertial sensor data. The sensor-based location is checked (and possibly adjusted) based on a comparison of the images. A database contains information about real-world objects in a field of view of the goggles-mounted source, and is used to generate icons or other graphics concerning such objects.

Systems, apparatuses, and methods are described which provide weapon sighted cameras. A camera can be mounted on a weapon and, after a set-up procedure, can acquire a target without using a weapon sight of the weapon.

The invention relates to a system to increase the effectiveness of direct fire weapon systems in targeting and destroying a target utilizing the military's existing direct fire weapon systems. The invention consists of a network which communicates with the devices of the invention and that are capable of directing the fire to a specific location.

An electronic device determines target information about a target and recommends a target based on the target information.

Systems, devices and non-transitory mediums that may display (a) a list of weapons or ammunition, allowing the user to select a type of weapon or ammunition; (b) a reticle selection screen allowing a user to select the type of reticle to be displayed; (c) adjustment controls allowing the user to adjust the positioning of the display reticle; (d) adjustment controls allowing the user to mark a position of a firearm reticle; (d) a range-to-target screen allowing the user to directly input range information or to employ a range finder; (e) a keypad allowing a user to enter a height estimate for the target; a scaling control screen to allow the user to input relative height information of the target; (f) an environmental information page allowing the user to enter the environmental factors; or (g) an optimized aim point or adjusted reticle based on such information.

According to an embodiment of the present invention is an sighting device based on camera comprising a camera module and a display module, wherein the camera module comprises main body, photographing unit mounted on the main body to photograph a target, flip cover for opening and closing the open side of the main body, infrared light emitting device installed in a predetermined area of the open side, laser light emitting device installed in a predetermined area of the open side and a first short-range communication module for short-range wireless communication, wherein the display module comprises screen for reproducing the image captured by the camera module in real time or near real time, manipulation unit for manipulating the image reproduced on the screen and a second short-range communication module communicated with the camera module.
