Ptkay, I'm former military (RAF) and have flown PARs and SRAs. They are simple if you are in practice at doing them.
Flying a PAR or an SRA, you don't respond to the instructions once you are established. There are too many instructions to respond to, either adjustments or confirmation that you are on centreline/glidpath. At short final the controller checks with tower, then clears you to land. At that point you just acknowledge the clearance, and as you approach your DH/MDH you look up, and if you can see the runway you land.
