These would actually be very useful if they add an anti-UAV mode. Infantry platoons will likely get small radars to detect UAVs, similar to how mortar attack detection radars are common in relevant units. These radars will be used to send a warning signal to the individual radios. All this infrastructure already exists to warn against incoming air, arty and mortar strikes.
It seems QN-202 is better than Pike as
* QN-202 is True Fire-and-Forget: The QN-202 uses an Imaging Infrared (IIR) seeker. The operator locks onto the target's heat signature, pulls the trigger, and can immediately duck into cover.
* Anti-Drone Capability: Because the QN-202 tracks the target itself via infrared, it is highly effective against erratic or fast-moving targets like FPV drones or hovering helicopters.
* No Wingman Required: It operates completely independently.
By contrast, the Pike uses Semi-Active Laser Homing (SALH). The target must be continuously "painted" with a laser designator by the shooter or a teammate until the missile impacts. If the person holding the laser has to duck into cover, the missile loses its target. Additionally, keeping a laser steady on a fast-moving drone at 2,000 meters is incredibly difficult, making the Pike less effective for air defense
But Pike is significantly lighter ~0.8kg while QN-202 is ~1.2kg.
So, even more capable I think QN-202 would be easily 5-10x cheaper than Pike .. considering how expensive of any weapons sytem in the US
