The AIM-9 'Sidewinder' is a heat-seeking, short-range, air-to-air missile. This particular one has a blue stripe around it which indicates it's a training round. A training round will have an active head but will not have a rocket motor or any explosive material. This allows pilots to simulate the use of the missile without having to actually carry live weapons onboard.
The AIS pod are one part of the Air Combat Maneuvering Instrumentation (ACMI) system. They are used, usually as part of an exercise or on a range, to collect information such as attitude, speed, climb rate, turn rate, roll rate, yaw rate and weapons release from each aircraft that has the pod fitted. This information is transmitted along with the aircraft's location to the Control and Computation Subsystem (CCS) which allows commanders to see the simulated battle unfold and the successful / unsuccessful kills or as part of debrief.
Both the highlighted pods whilst different in operation are part of the same system. The Low Altitude Navigation and Targeting Infrared for Night (LANTIRN) system is standard fit on all F-15E Strike Eagles but is due to be replaced by the Sniper XR Advanced Targeting Pod (there won't be a replacement for the navigation pod).
The navigation pod provides both Terrain Following Radar (TFR) and Forward-Looking Infra-Red (FlIR) allowing the F-15E to operate at altitudes down to 100 feet in all weathers, night or day. It has five selectable modes: Normal, Weather, ECCM, Low Probability of Intercept (LPI), and Very Low Clearance (VLC). The images from the pod are displayed on either the multi-function display in the cockpit or directly to the Heads Up Display (HUD). In a day time low level sortie the navigation pod wouldn't be used.
The targeting pod also uses Forward-Looking Infra-Red (FlIR) to provide a high resolution image stabilised picture of the target. Once the target has been found and indentified a laser designator and range finder is used to track the target.
The electronic attack training pod unlike the other items listed above is not a standard fit item on the F-15E. It's used as a threat simulator in training sorties.
