Who gives a flying f#*k? Medals and post nominal for what exactly? Nothing extraordinary in first being able to pass all your kit musters and learn how to do the marching thing then not failing trade training. After that spend some time doing some sea time but also pissing it up in harbour etc. Medals for something above and beyond, post nominals to show you have some form of highly specialised or rare qualification etc. that sets you apart or above the run of the mill.
