Its nice to be appreciated SJ though don't lay it thick for me, keep some for yourself. I'm sure even you know a thing or two about something useful.
As you quite rightly say though*, its not a p!ssing contest. Its a healthy dose of inter-service rivalry, something that has been going on for years and sees no sign of stopping.
Of course the internet is a fickle beast and what would in a bar or crewroom be immediately obvious as banter can come across as slightly more edged due to the relatively limited written format in which comments are made.
*(See, I told you you might know something useful.)
