Nope, watch the demos of the Rheinmetall HEL, the system specifically and accurately targets the pilot of manned aerial vehicles, and the guidance and navigation systems of manned and unmanned aerial vehicles, including rockets. There is no way to make ball bearings, hinges, defrost patches, exhaust ducts, inlets, IR pod lenses, radomes, etc... entirely reflective and still have a functional navigatable vehicle.
It will eat through a solid steel hinge or ball bearing in seconds, it will kill navigational equipment in fractions of a second.
Second factor is that in Germany, the HEL works together with other weapons systems, like the Lynx, which is a high rate of fire gatling machine cannon that can be deployed in the same redundant targeting network, and can also work in arrays to engage multiple targets at once. The yield and range are different, but it's designed to finish targets that are disorientated or decommissioned with the HEL units.
These things are pretty effective. Weapons that are approaching beyond the targeting possibilities of ballistic weapons, get slowed down and disabled by the HEL which works at light speed, for instance a missile or a supersonic fighter. The HEL does not depend on radar targeting, it uses all known kinds of targeting, and is really precise, fast and accurate. When the enemy object is slowed down or disabled, the Lynx can wait until it in range and can be successfully tracked for ballistic weapon targeting, and then finish it off before it can cause heavy collateral damage. Because of the portability, low installation requirements, fast deployment, mobility, and deployment in redundant arrays, it's a pretty formidable defence system. It's also relatively low cost, and requires very little operators and maintenance. It's a pretty modern weapon, also because it's a defence weapon, it's specifically made to protect, which intellectually is a huge step forward in weapons design. Most weapon systems are made to attack and destroy indiscriminately, and therefore lack in defensive capabilities. The focus of development with these modern weapons systems is completely different, there is only one field of efficiency to explore for developers, the scope is narrower, which increases the development and operational value.
