With Sven seeing and facing a covenant invasion, i think he will be very pressing for new solutions when writing his after action report. Mostly nudging toward reviewing system commanders (nudge Yao), and new emergency protocols (the current evac on the world is not going quite well).

I don't think it would change anything but someone might start listening. Its also a very Sven thing to do. Beside Command did want to increase his rank, they just wanted that he gained more experience first. Its gonna be the fastest promotion from Lieutenant probably
