The problem with the targeting lasers and dust is that the dust disperses the laser. Since they are guidance and rely on the laser being reflected back the dust blocks it. A laser weapon on the other hand would slice through the dust just like it would body armor, flesh, and a foot of solid steel.
As for targeting. There are existing weapons targeting systems that can cut through it. Just use those.
There is linkage se5a. Check the first page. I have several links in one of my Posts.
