Editing Noise Marines (section)

===Third Edition===
This is where things get interesting. At the onset of Third, Noise Marine weapons get a weird change getting variable strength but low AP and the weapons were more restricted: noise marines were armed primarily with the sonic blaster, with some upgrade options to blastmaster or doom siren, while the champion could still take any of the sonic weapons - including the blastmaster! Also note that Noise Marines were a Heavy Support choice here instead of an elite, which was changed with the new codex.

Then 3.5 came along and changed that dramatically: sonic weaponry were revised again removing their random strength and the blastmaster specifically gained it's double profile here. They also become flat upgrades to other weapons on models with the Mark of Slaanesh or on vehicles dedicated to Slaanesh. The implication here was that for a fee, most models could upgrade or straight up buy better bolters, flamers or auto-cannons. It also meant there were vehicles with sonic weapons, making the Emperor's Children somewhat OP. Noise Marines specifically could be taken as troops if the lord leading the army had a mark of Slaanesh and any unit numbering 6 models could take an aspiring champion for free.
