My understanding was that an individual was awarded the MSM on their track record based on previous ACRs/OOA reports and covered their contribution to the wider aspects of service life in addition to their professional duties It was not based on a particular recommendation by a single individual. My reason for saying that is one of my colleagues was awarded the MSM and our then OC Supply tried to big himself up by intimating that it was he (the Jellyfish) who had nominated my colleague. As for who was considered for the award, I believe it was based on holding a particular rank (e.g. FS/WO) and being a 'certain' age so the pool of candidates was relatively small and candidates were only considered once--although I do expect to be corrected.
