Javelins, by the way, say hyped shit, moreover, according to the reviews of Ukrainian soldiers. In Mariupol, the Javelins did not seem to be able to burn a single Russian tank. There are a lot of conditions for successful operation, which are difficult to put together in a real battle.
Javelins need distance. In urban battles NLAW works better. Still needs at least 20 meters. Good thing is that Ukrainians have a wide range of anti-tank weapons.
Javelin is heavy, expensive and not very effective, there are problems with target acquisition. NLAW is very unreliable and frankly weak against a tank with modern dynamic armor. In general, the initial bet on hand-held anti-tank systems did not work, the main tank losses were from artillery.
Funny how bring up Mariupol again, a city that for two months Russians were not able to take with a 10-fold advantage in numbers.
During the assault on Mariupol, Russia did not even have a two-fold numerical superiority. This is perhaps Russia's biggest problem in this operation, with overwhelming technical superiority, there is simply not enough infantry. However, the current pale appearance of Ukraine and NATO standards is all the more dramatic.
