Leveraging COTS Products for Maneuverable Aerial Identification
Although ground troops are equipped with identification, friend or foe (IFF) devices, many fratricide cases still occur during air-to-ground operations. This research project explored how relatively inexpensive commercial off-the-shelf (COTS) technologies can be leveraged to construct a maneuverable aerial identification friend-or-foe (MAIFF) device.

Ground troops are equipped with identification-friend-or-foe (IFF) devices. When they are engaged in a firefight, they seek cover and concealment, and consequently, their attached IFF are also covered and concealed. The situation is aggravated when firefights happen at night in vegetated areas, presenting additional challenges for air force pilots when conducting close air support (CAS) operations. Hence, ground troops need to be able to deploy a visual reference above the canopy of vegetation while they remain concealed physically. By contrast, the absence of visual reference may result in the delay of pilots positively identifying the friendly forces; provide additional time for enemy action; expose aircraft unnecessarily; and potentially cause fratricide.
This research project explored how relatively inexpensive commercial-off-the shelf (COTS) technologies can be leveraged to construct a maneuverable aerial identification friend-or-foe (MAIFF) device. It would serve as a visual reference to enhance the situation awareness (SA) of pilots performing night CAS operations. This maneuverable device does not have a direct back azimuth to the soldier’s specific location.
A systems engineering approach was employed to produce a prototype MAIFF using a sub-250 gram quadcopter drone mounted with infrared lights and other electronic and non-electronic parts—referred to in this project as the lamp. Hence, a MAIFF device is composed of a lamp mounted on a drone. The lamp weights 17 grams and has a diameter of 50.58 mm and a height of 25.59 mm. The lamp uses nine pieces of 3 mm infrared lights powered by two 3V coin batteries. The illumination provided by the lamp is invisible to the naked eye. It can only be seen using a night vision device. Its illumination can last six hours and visible up to one mile away. The lamp’s mounting design is stable and versatile, enabling the lamp and the drone to fly as one unit. This study designed a scenario-based test to measure whether the use of the MAIFF device improves the situation awareness of troops—particularly for pilots conducting night CAS operations. The conduct of the actual scenario-based test is not part of the study.
Nevertheless, the designed test may serve as a ready reference for regular training between major services, or during joint training exercises involving partner nations. The research study recommends conducting a scenario-based test as a step towards MAIFF adoption by military organizations. Testing the MAIFF will determine whether it enhances situation awareness, reduces the occurrence of fratricide, and increases the lethality of close air support operations. The test can be done during regular training with the army and the air force, or during joint training exercises between the armed forces of the Philippines and the United States.
In limited visibility situations, runway lights and approach lights significantly help pilots to connect the data from the cockpit to the physical runway on the ground. In approaching for a landing, the first runway light that becomes visible significantly influences the final decision of the pilots. Visual reference facilitates an accurate and safe landing. This principle is also present in conducting close air support (CAS) operations in limited visibility situations.
CAS is needed when friendly ground forces are engaged with hostile enemy in close proximity. It entails a well-coordinated delivery of air munitions in tandem with the fire and maneuver of the ground troops. Before the pilots fire a weapon, they need ample information about the location of the friendly forces and the enemy. Pilots have initial data from the cockpit. A visual reference from the actual terrain will contribute to a safe and effective conduct of CAS. By contrast, the absence of visual reference may result in the delay of pilots positively identifying the ground forces; provide additional time for enemy action; expose aircraft unnecessarily; and potentially cause fratricide.
