Also, despite the original question being the result of a misreading of a thread on my part, I think the question is still worth an official ruling. As written, rule appears to apply to individual squads and platoons the same way, and thus reduces the incentive to deploy as a platoon. That said, it does make sense that dispersed squads with Heavy Burst weapons could inflict more damage on conventional infantry formations, so that may have been as intended.
