No. 62/222,475, filed Sep. 23, 2015, titled ELECTRONIC DRONE DEFENDER-WIRELESS JAMMING AND SIGNAL HACKING, the disclosures of which are incorporated by reference in their entirety herein. 
    
    
     BACKGROUND 
     The following relates generally to the electronic countermeasure arts, the unmanned autonomous vehicle arts, signal jamming arts, communications arts, satellite navigation and communication arts, law enforcement arts, military science arts, and the like. It finds particular application in conjunction with the jamming and hijacking of drones, and will be described with particular reference thereto. However, it will be understood that it also finds application in other usage scenarios and is not necessarily limited to the aforementioned application. 
     Unmanned or autonomous aerial vehicles (“UAV), more commonly known as “drones”, have become more and more prevalent in both the military and civilian context. Current, commercially available drones embody technology that was until recently, solely within the purview of governmental entities. The drones available to the civilian and military markets include navigation systems, various types of eavesdropping components, high-definition or real-time video output, long life lithium batteries, and the like. Furthermore, current civilian models may be operated by any individual, without regarding to licensing or regulation. 
     The propagation of civilian drone usage has resulted in invasions of privacy, interference with official governmental operations, spying on neighbors, spying on government installations, and myriad other offensive operations. Military usage of drones, including armed drones, has increased substantially as battery storage has increased and power consumption has decreased. This widespread use of drones has led to security and privacy concerns for the military, law enforcement, and the private citizen. Furthermore, drones have substantially decreased in size, resulting in smaller and smaller, while the capabilities of the drones themselves have increased. This poses a security risk for security personnel as the operator of the drone may be far away, making the determination of the operator&#39;s intent particularly difficult to ascertain. 
     The drones in use typically operate using multiple frequency bands, some bands used for control signals between the drone and the operator, GPS/GLONASS signals for navigation, and other frequency bands for video and/or audio signal transmissions. This use of multiple frequencies results in difficulty in effectively tailoring a jamming signal directed solely to the offending drone, without negatively impacting other, non-offensive radio-frequency devices. 
     Furthermore, current commercially available jammers, while illegal in some jurisdictions, are generally omnidirectional in nature. To avoid issues relating to non-offensive devices, these jammers typically are limited in radius from less than a meter to 25 meters. Those jammers having larger effective radii for signal jamming or denial require substantial power (plug-in/non-portable) or are bulky. A common problem with all of these jammers is their inability to specifically target a drone, while allowing non-threatening devices to remain operational. Furthermore, due to the distances, and heights, at which drones operate, the portable jammers currently available lack the ability to effectively jam signals that may be used by the drones. For example, such commercially available jammers for Wi-Fi or GPS will propagate a jamming signal circularly outward, rendering the user&#39;s own devices inoperable while within that radius. The unintended consequences of such jamming may cause vehicle accidents or aircraft issues, depending upon the strength and radius of the jammer being used. 
     In addition to the foregoing problems, current jammers lack the ruggedness associated with field operations. That is, the commercially available jammers are delicate electronics, not designed for use by soldiers in the field. As noted above, the commercial jammers currently available further utilize multiple antennae, each directed to a different frequency band. These are not ruggedized pieces of equipment, capable of being utilized in field operations by law enforcement, security, or military. The multiple antennae are prone to breakage during transport. Those rugged military or law enforcement jammers that are available are portable in the sense that they are backpack or vehicle born devices, requiring substantial training to effectively operate. 
     Previous attempts at hand-held or portable jammers utilized standard form-factors for hand-held weapons. However, these designs are intended to compensate for recoil as the weapon fires. Rifle form-factors typically utilize a two hand approach, with the hands being spaced apart to steady the rifle when firing. This hand placement, with the weight of the average weapon, can be tiring, particularly when holding the weapon on target. Generally, because the weapon fires so quickly, the aforementioned design does not necessarily adversely affect its use. However, with directed energy weapons, which must remain on target while active, this displacement of at least one of the hands away from the body of the operator, places considerable strain on the extended arm. 
     Thus, it would be advantageous to provide a ruggedized form factor directional drone jammer that provides a soldier or law enforcement officer with simple, targeted anti-drone capabilities. Such a jammer is portable, including power supply, and comprises a rifle-like form allowing the soldier or law enforcement officer to aim via optic, electronic or open sights at a target drone for jamming of the drone control and/or GPS signals, while preventing interference for other devices utilizing the jammed frequencies. Furthermore, it would be advantageous to provide a suitable form-factor that relieves arm strain while maintaining aim on a targeted drone.

Furthermore, the embodiments disclosed herein may be implemented without software, hardware, or other signal analysis means, enabling a soldier or law enforcement officer to use the portable countermeasure device without substantial training. Such a simplified implementation further ruggedizes the portable countermeasure device for use in harsh environments where weather, lack of resupply, insurgents, criminals, or the like, may operate. 
     Referring now to  FIG. 1 , there is shown a functional block diagram of a portable countermeasure device  100  in accordance with one exemplary embodiment of the subject application. As illustrated in  FIG. 1 , the portable countermeasure device  100  may be implemented in a firearm-like form factor, providing ease of use and familiarization with the user. Accordingly, the portable countermeasure device  100  provides a soldier or law enforcement officer with the ability to specifically target a particular drone with disruptive signals, while minimizing the impact of the generated signal on other, non-targeted devices. It will be appreciated that the various components depicted in  FIG. 1  are for purposes of illustrating aspects of the exemplary hardware are capable of being substituted therein. 
     It will be appreciated that the portable countermeasure device  100  of  FIG. 1  is capable of implementation in a variety of handheld or portable form factors, and the illustrations depicted and discussed hereinafter provide exemplary, and non-limiting, form factors contemplated hereunder. As shown in  FIG. 1 , the portable countermeasure device  100  comprises a body  102  including signal disruption components  104 , e.g., at least one signal generator  106  and at least one amplifier  108 . The illustration of  FIG. 1  depicts a portable countermeasure device  100  that utilizes a dual-grip configuration, having a first grip  114  in location typical with the typical pistol-grip rifle, and second grip  115  in relatively close proximity to the first grip  114 . In some embodiments, as illustrated hereinafter, the first and second grips  114  and  115  may be adjacent each other, with the second grip  115  cantilevered or angled forward, towards the front of the device  110  and the first grip  114  cantilevered or angled back towards the rear of the device  110 . In other embodiments, as will be appreciated by those skilled in the art, the body  102  may, for example and without limitation, resemble a commonly used rifle, including, without limitation, M4 carbine, M14, AR-platform, or the like, comprising an upper receiver and a lower receiver, as well as other rifle designs, as will be appreciated by those skilled in the art including, for example, modular rifle designs, standard rifle designs, and the like. Depending upon the configuration of the portable countermeasure device  100 , the signal disruption components  104  may be contained in the upper receiver, the lower receiver, or both. 
     The body  102  may be constructed of non-metallic materials, i.e., ballistic plastic, carbon fiber, ceramics, etc., or suitable non-transmissive metallic composites. The body  102  may be implemented in a suitable form factor with which soldiers and/or law enforcement personnel are already familiar, e.g., the aforementioned M4 carbine, AR-platform, AK-platform, SCAR, bullpup, etc. It will be appreciated that the width, length, and height of the body  102  may be dependent upon the size and number of generators  106  and amplifiers  108  either integral therein or externally affixed thereto. According to one embodiment, a multifunctional cell is formed as the body  102  to provide both structural support/shape of the portable countermeasure device  100  as well as supply power to the components therein. A suitable example of such a multifunctional cell is provided in PCT/US2013/040149, filed May 8, 2013 and titled MULTIFUNCTIONAL CELL FOR STRUCTURAL APPLICATIONS, the entire disclosure of which is incorporated by reference herein. In accordance with another embodiment, the portable countermeasure device  100  may include multiple signal disruption components  104  to combat a variety of potential targets, e.g., receivers of improvised explosive devices (IEDs), commercial drones, military drones, or other portable electronic devices of enemy combatants or suspects, e.g., cellular phones, GPS/Satellite-based navigation devices, remote control detonators, etc. A suitable example of a portable countermeasure device  100  that includes multiple signal disruption components  104  within the body  102  is depicted in  FIG. 2A  et seq., as discussed below. 
     The portable countermeasure device  100 , as shown in  FIG. 1 , includes a first activator  110 , located adjacent to the first grip  114 , and a second activator  112 , located adjacent to the second grip  115  on underside of the body  102 . It will be understood that the portable countermeasure device  100  may be implemented with a single activator, whereby multiple disruptive signals are generated via the activation of the single activator. The activators  110 - 112 , as will be appreciated, is operable to close a circuit or “firing mechanism” (not shown) to allow power to flow from the power source, e.g., backpack (not shown), AC power (not shown), or optional, battery pack (not shown), to the signal generator  106  and amplifier  108  of the signal disruption components  104 . It will be appreciated that the activators  110 - 112  may be implemented as typical firearm triggers, toggle switches, spring-loaded buttons, or the like. According to one embodiment, the first activator  110  is operable to activate control circuitry for disruption of control frequency bands, while the second activator  112  is operable to activate control circuitry for disruption of GPS/navigation bands. An example implementation of the dual activators  110 - 112  is embodied in the portable countermeasure device  200  of  FIGS. 2A-3F , discussed below. 
     In accordance with one embodiment, the signal generator  106  and corresponding amplifier  108 , may be configured to generate signals from DC to 30 GHz. In another embodiment, a signal generator  106 , with corresponding amplifier  108 , is incorporated to generate disruptive signals in the, 70-75 MHz, 400-500 MHz, 800-900 MHz, 900-1000 MHz, 1000 MHz-1.8 GHz, 2.0 GHz-2.6 GHz, 5.0-5.6 GHz frequency ranges, or other known control/navigation signal frequency ranges. In one particular embodiment, a signal generator  106  for each of the 72 MHz frequency band, the 400 MHz frequency band, the 800 MHz frequency band, the 900 MHz frequency band, the 1.2 GHz frequency band, the 1.5 GHz frequency band, the 2.4 GHz frequency band, and the 5.8 GHz frequency band, with corresponding amplifiers  108  are incorporated into the portable countermeasure device  100 . Additionally, the signal generator  106  may be in communication with memory (not shown) that stores alternative command signals for spoofing or hacking, as will be known in the art, a particular control frequency. In such embodiments, the signal generator  106  may be operable to transmit a different navigation signal (altering the coordinates the drone is receiving from navigation satellites/commands), transmit a control signal indicating the drone should land or return to home, or the like. It will be appreciated that such signals generated via the signal generator  106  may be output in addition to noise, jamming, or the like, or in place thereof. 
     In accordance with the example embodiment of  FIG. 1 , the optional battery pack (not shown) supplies suitable power to the disruptions components  104  of the portable countermeasure device  100 . In one non-limiting example, the battery pack may be implemented as a rechargeable battery, including, for example and without limitation, a lithium-ion battery, a lithium ion polymer battery, a nickel-metal hydride battery, lead-acid battery, nickel-cadmium cell battery, or other suitable, high-capacity source of power. In other embodiments, a non-rechargeable battery may be utilized, as will be appreciated by those skilled in the art. According to one exemplary embodiment, the battery pack is implemented in a magazine form factor, capable of insertion into a battery well (similar to the magazine well of the lower receiver of a rifle). It will be appreciated that such an implementation will be natural to a soldier or law enforcement officer, allowing utilization of existing magazine carrying devices for carrying additional battery packs, familiarity with changing a battery pack, as well as maintain the balance of the portable countermeasure device  100  similar to those rifles with which the soldier or law enforcement officer is most familiar. 
     In accordance with another embodiment, the portable countermeasure device  100  may utilize an auxiliary cable to a backpack power supply, a remote power source, a portable generator, fuel cell, vehicle interface, or the like. As shown in  FIG. 1 , a suitable coupling  117  is illustrated as affixed to the buttstock  103 , enabling the attachment of a suitable power cable from various sources, e.g., a battery stored in a backpack, hip/fanny pack, secured to MOLLE webbing, or the like. Furthermore, the skilled artisan will appreciate that the battery pack is not limited in form and can be complementary to the form-factor of the portable countermeasure device  100 , for example, similar to a rectangular magazine, tubular magazine, and the like, as well as being integrated within the body  102  of the portable countermeasure device  100 , i.e., a structural battery as discussed above. 
     According to another embodiment, the portable countermeasure device  100  may include a display  120  operable to display remaining power levels of the battery pack, effective range of the output of the signal disruption components  104  relative to power supply level, or the like. This optional display  120  may be connected to control components (not shown), and be customized to display the frequency selected for output by the jammer components  104 . In such an embodiment, the display  120  may be implemented as an LED, LCD, OLED, or other suitable display type. In accordance with one embodiment, the display  120  of the portable countermeasure device  100  may be implemented as a visual indicator associated with operation of the various components of the device  100 . It will be appreciated that as the portable countermeasure device  100  does not provide physical recoil when operated, the display  120  provides visual feedback to the operator. As indicated above, one or more LEDs, or other suitable visual indicators, may be utilized, indicating, for example and without limitation that individual circuit cards are powered up, that individual circuit cards are within specified limits, that power is on to the operating/selected antennae, which antennae are operating, and the like. 
     In accordance with another embodiment, the portable countermeasure device  100  is equipped with a haptic feedback component  121 , configured to provide haptic feedback through the body  102  (or grips  114 ,  115 ) to the operator when the portable countermeasure device  100  is active. In varying embodiments, the haptic feedback component  121  may be activated when one or more triggers  110 ,  112  are engaged and power to the signal disruption components  104  is on. In such embodiments, the haptic feedback generated by the component  121  may differ so as to indicate which antenna(e)  122  is engaged. As with other directed energy devices, e.g., lasers, RF generators, radar jammers, etc. having weapons form factors used in electronic warfare, the portable countermeasure device  100  of the subject application the does not provide any observable recoil when activated. Accordingly, the haptic feedback component  121  may provide varying feedback to triggers  110  and/or  112 , grips  114  and/or  115 , buttstock  103 , etc., indicating activation of the portable countermeasure device  100 . 
     The portable countermeasure device  100  depicted in  FIG. 1  utilizes a single, multi-function directional antenna  122 , extending outward from the body  102  in a direction away from the user. It will be understood that other embodiments, as discussed below, may utilize multiple directional antennae in accordance with the number of disruptive signals to be generated, the types of disruptive signals, desired range, and the like, as illustrated in  FIGS. 2A-3F , described below. It will be appreciated that, maintaining a suitable comparison to a rifle, the antenna  122  replaces the barrel of a rifle, thereby maintaining familiarity and ease of operation by the soldier or law enforcement officer. In accordance with some embodiments, the antenna  122  may be “hot-swappable” or “replaceable” in the field, allowing for different directional antennae to be used by the portable countermeasure device  100  in accordance with the battlefield conditions. For example, the distances involved in commercial drone disruption may utilize less power-intensive disruptive signals than military drone disruption. In such an embodiment, a suitable antenna may not need to be as large, or a different design antenna may be used. In another example, in the event that the antenna  122  is damaged while in the field, an expedient repair capable of being performed by the soldier or law enforcement officer is replacement of the antenna  122 , as opposed to having to submit the portable countermeasure device  100  to an armorer or electronics specialist for repair, thereby keeping the portable countermeasure device  100  operative. 
     In one particular embodiment, the antenna  122  is implemented as a combined, high-gain, directional antenna having a helical cross-section. Other suitable directional antenna, e.g., Yagi, cylindrical, parabolic, long period array, spiral, phased array, conical, patch, etc., are also capable of being utilized in accordance with the disclosure set forth herein. 
     Affixed to the top of the body  102 , either fixed thereto, or removably attached, e.g., attachments to a rail (shown in  FIGS. 2A-3F ), are “iron sights”  124 A (with a corresponding sight  124 B attached or fixed to the end of the antenna  122 ), allowing for aiming by the soldier or law enforcement officer of the portable countermeasure device  100  at a target drone. In other embodiments, particularly when the top of the body  102  includes the aforementioned rails, a wide or narrow field of view optical sight may be utilized to allow the soldier or law enforcement officer to target drones beyond the normal field of vision. To avoid unintentional disruption of nearby devices outside the disruption cone  126  directed by the antenna, the sight  124 A and/or  124 B may be constructed of a suitable non-metallic material. The disruption cone  126  may range from 0 degrees to 180 degrees, including for example and without limitation, 0 to 120 degrees, 0 to 90 degrees, 0-45 degrees, 20 to 30 degrees or variations thereof. The effective range of the portable countermeasure device  100  may extend outward from the antenna  122  at varying ranges, from 0 meters outward greater than or equal to 400 meters in accordance with the power supplied to the disruption components  104 . Accordingly, it will be appreciated by those skilled in the art that the maximum range of the portable countermeasure device  100  may be extended or reduced in accordance with the amount of power supplied to the disruption components  104 , the ratio of power to time on target, and the like. 
     In operation, the soldier or law enforcement officer will target a drone hovering or flying in an unauthorized area by aiming the antenna  122  of the portable countermeasure device  100  in a manner similar to a regular firearm. That is, the soldier or law enforcement officer, using the iron sights or optical sights  208 , directs the antenna  122  of the portable countermeasure device  100  toward the drone. After ensuring that sufficient power is available, and the drone is within the effective range of the portable countermeasure device  100 , the soldier or law enforcement officer activates the activator  110  (for all control frequency bands) and/or the activator  112  (for all GPS/navigation frequency bands) to activate the control circuit (not shown), which regulates the power from a battery or other power source to the disruption components  104 . In an alternative embodiment, a single activator (not shown) may control activation of all disruption components  104 , thereupon simultaneously or sequentially generating disruptions signals as described herein when the activators  110  and  112  are activated. When disrupting multiple frequency bands, e.g., control signals, Wi-Fi and/or GPS, multiple disruption signal generators  106  and amplifiers  108  are activated to produce the desired disruption signal, e.g., noise, spoofing, alternate commands, alternate coordinates, etc., on the selected frequency bands. 
     The disruptive signal is then directed through the single antenna  122  (capable of handling multiple frequency bands) or multiple antennae toward the drone at which the portable countermeasure device  100  is aimed. The disruption cone  126  then extends outward from the portable countermeasure device  100  toward the drone, disrupting control and GPS signals effectively negating the presence of the drone in the unauthorized area. Alternative embodiments disclosed herein include generating, via the signal generator  106 , alternative commands to the drone, instructing the drone to land, change direction, change video broadcast stream, stop video streaming/recording, thereby overriding the original control signals. Furthermore, the portable countermeasure device  100  may be configured to transmit altered navigation coordinates, confusing the drone or forcing the drone to leave (or travel to) a particular area. The soldier or law enforcement officer then maintains his/her aim on the drone until the drone falls, retreats, loses power, or the like. The activator(s)  110 - 112  may then be deactivated by the law enforcement officer or soldier and the disabled drone may then be recovered by the appropriate authority for determination of the owner. 
     According to one example embodiment, the portable countermeasure device  100  includes hardware, software, and/or any suitable combination thereof, configured to interact with an associated user, a networked device, networked storage, remote devices, detector systems, tracking systems, and the like. In such an example embodiment, the portable countermeasure device  100  may include a processor, which performs signal analysis, ballistic analysis, or the like, as well as execution of processing instructions which are stored in memory connected to the processor for determining appropriate signal generation for disruption, power supply management, and the like. It will be appreciated that the inclusion of a suitable processor is optional, depending upon the ruggedness of the underlying implementation of the portable countermeasure device  100 . Further, it will be understood that separate, integrated control circuitry, or the like, may be incorporated into the portable countermeasure device  100  so as to avoid interference of operations by the disruption components  104 , or the like. 
     According to another example embodiment, the portable countermeasure device  100  may include a selector control (not shown), which may be located on the exterior of the portable countermeasure device  100 . Such a selector control may be operable to select a frequency or frequencies to be generated by the at least one signal generator and amplified by the corresponding at least one amplifier  108 . In accordance with one alternate embodiment, a variable amplifier may be used, whereupon power supplied to the signal generators  106  is modified, without increasing the power drain of the portable countermeasure device  100 . It will be appreciated that the selector control may be implemented to provide ease of use to the soldier or law enforcement official in the field to reflect the desired target of the portable countermeasure device  100 . 
     Turning now to  FIGS. 2A-3F , therein are illustrated three-dimensional and line views of an example portable countermeasure device  200  utilizing a multi-antenna ( 202 ,  204 , and  206 ) implementation of according to one embodiment of the subject disclosure. As shown in  FIGS. 2A-3F , the portable countermeasure device  200  instead of utilizing an existing firearm, utilizes a suitable dual-grip firearm-like form factor body  208  to which the various components are attached, e.g., custom rifle stock. The dual-grip form factor body  208  includes an attachment rail  212  for affixing optics, e.g., red dot sights, iron sights, holographic sights, or the like, as well as additional components. Suitable rails  212 , include, for example and without limitation, Picatinny, Weaver, NATO accessory rail, KeyMod, M-LOK, and the like. In this embodiment, the disruption components (not shown) are inserted within the dual-grip, firearm-like, form factor body  208  in place of the standard firearm components, e.g., the receiver(s) and barrel. This reduces the cost of implementation of the subject disclosure, while preserving the familiarity with a common weapon for the soldier and/or law enforcement personnel. 
     The multiple antennae  202 ,  204 , and  206  illustrated in  FIGS. 2A-3F , are coupled to the body  208  adjacent a reflector  214 , which directs signals away from the operator and toward the target. The antennae  202 ,  204 , and  206  may correspond, for example and without limitation, to a Yagi antenna, a proprietary double helical antenna, an LPA, and/or various combinations thereof, depending upon the frequencies being targeted by the portable countermeasure device  200 . The body  206  further includes a buttstock section  210  incorporating the connector  117 , as discussed supra. In addition to the foregoing, the body  208  of the portable countermeasure device  200  illustrated in  FIGS. 2A-3F  utilizes the above-mentioned dual-grips  114  and  115 . It will be appreciated that the configuration of the first grip  114  angled toward the buttstock  210  and the second grip  115  angled toward the antennae  202 ,  204 , and  206  allow the operator to easily control and aim the device  200  towards an intended target. As shown, the second grip  115  extends downward from the trigger guard of the first trigger  110 , and allows an operator easy access to the second trigger  112 , without requiring the operator to adjust his/her grip on the device  200 . Also depicted in  FIGS. 2A-3F  is a selector switch  216 , optionally included to allow for the operator to select which frequency or frequencies to be jammed by the portable countermeasure device  200 . That is, according to one embodiment, the selector  216  is communicatively coupled to the internal disruptor components  104  of the portable countermeasure device  200 , allowing the operator to enable jamming of one or more frequencies.  FIGS. 6A, 6B, and 6C  provide three-dimensional depictions illustrating varying embodiments of the portable countermeasure device  200 , including the aforementioned dual-grips  114  and  115 . 
     As illustrated in  FIGS. 6A-6C , the portable countermeasure device  200  may utilize varying embodiments of the antenna  206 , as shown therein. In particular, the antenna  206  is representative of a Yagi antenna, suitably configured, in one embodiment, to transmit signals in the 400-500 MHz range, with particular emphasis on the 433 MHz frequency. The antenna  206 , as shown in  FIGS. 6A-6C  is capable of implementation using a variety of shields, protecting the antenna from damage during transport and use. A more detailed illustration of one embodiment of the antenna  206  is shown in the three-dimensional views of  FIGS. 7A-7E , and the line drawings of  FIGS. 8A-8E . 
     It will be appreciated that the embodiment of  FIGS. 2A-3F , and  FIGS. 6A-6C  utilizes disruption components  104  located within the body  208  of the portable countermeasure device  200 . However, in an alternate embodiment, as depicted in  FIGS. 4 and 5 , the disruption components  104  may be removably coupled via connector  117  to the portable countermeasure device  200  externally, as shown. 
     The portable countermeasure device  200  of  FIGS. 2A-3F  utilizes dual grips  114  and  115  with corresponding dual activators  110  and  112  for respective disruption of control signals and GPS/navigation signals.  FIGS. 9A and 9B  provide close-up views of an example implementation of the dual grips  114  and  115  with associated dual activators  110  and  112  on the portable countermeasure device  200 . The rendering in  FIGS. 9A-9B  further illustrate the dual grips  114  and  115  of the portable countermeasure device  200 . As shown, the first grip  114  is configured to enable the operator to engage the first trigger  110 . The cantilevered or forward-angled second grip  115  is configured to enable the operator to engage the second trigger  112 , without requiring the operator to adjust his stance or wielding of the device  200 , i.e., the operator does not have to move his hands from the grips  114  or  115  in order to engage the disruption components  104 . In accordance with one embodiment, the portable countermeasure device  200  may be modular, rugged, and portable, capable of being transported by a soldier or law enforcement official without damage to the antenna  202 - 206 , the body  208 , optics, rail attachments, etc., may be disassembled and stored in the backpack depicted in  FIG. 5 . 
       FIGS. 10A-10F  provide a three-dimensional view of the body  208  of the portable countermeasure device  200  in accordance with one embodiment of the subject application.  FIGS. 11A-11F  provide a further detailed line view of the body  208  of the portable countermeasure device  200  in accordance with the embodiment of  FIGS. 10A-10F . As will be appreciated, the body  208 , comprising the dual grips  114  and  115 , buttstock  203 , rails  212 , dual-triggers  110 - 112 , and connection  117  is illustrated without the reflector  214 , or antennae  202 - 206 . Accordingly, the body  208  comprising the above-identified components, as illustrated in  FIGS. 10A-11F  is capable of adaptation to a plurality of weapons, including, for example and without limitation, low-recoil ballistic weapons, directed energy weapons, and the like. It will be understood that the example implementations of  FIGS. 1-11  are non-limiting examples of possible firearm-like form factors implemented as the portable countermeasure device  100  according to the disclosures contained herein.
