No, I think it is every important to keep a decent ratio of military within the 3rd line including the ADM(Mat) world as it maintains ties to the CAF and injects a certain raison d'etre into organizations who through complacency may lose sight of the fact that they exist to support CAF operations
That isn't to say that the civilian staff at either depot (or the CFADs) do not work hard to support CAF operations either, as on a individual level or at as a group I have seen them come together and get things done for the folks doing the business. Leaving ADM(Mat) aside 3rd line is really the last bastion of CAF influence on the day to day Defence Supply Chain and keeping the CoC and some of the key folks in their military allows it to remain responsive to CAF demands and by proxy accountable. It it that flexibility aspect that
@rmc_wannabe mentions in tier post that we IMHO need at our 3rd line orgs
Besides, if there are no Cpl/MCpls who is going to do Duty HPR MMT? Although is there really a need for a duty HPR MMT if there is no way to ship the item until the next business day?
