Boy howdy time to do some crit.
MST Romeo-7 has been granted clearance to bypass prior authorization to utilize all resources save paramilitary as a means of containing RPC-XXX.
I would reword this, something like "MST Romeo-7 has been granted clearance to contain RPC-XXX by any means necessary, with the exception of paramilitary resources.
RPC-XXX refers to an anomalous event that occurs when an organized celebratory gathering involving more than 250 persons is held within the vicinity of former battle sites.
I would take the first two sentences of this paragraph and merge them with the notes, to better exemplify the exact conditions of an RPC-XXX scenario.
RPC-XXX-X's descriptions
This suggestion is up for discussion, but play around with moving the descriptions before and after the description of the anomalous event and see how it would better fit the narrative you're trying to write.
Current Known Ranges of Manifestation
Add examples of manifestations that lead to these conclusions, scenarios that formed when this RPC first appeared.
overall tone of the article
This article has potential, however it feels incomplete; it has the makings of a really, really terrifying uncontrollable RPC, however there are no specifics to it. I would play around with the arrangement of the paragraphs a bit, and add some example scenarios that have happened under the effects of this RPC.
