DS answer-They all train together in mixed platoons so in theory they are all the same, with little quirks and regimental traditions the only definable difference.
(although in actual fact the collies **** sheep, the grens love the sound of their own voices and are a little on the gay side and the Irish guards are all well endowed, handsome rescuers of damsels in distress. Women want them and men want to be them. In no way am I biased)
We are all pretty similar, I don't know about the other two but the bullshit level in the Grenadiers is certainly not as high as you would experience in some units, RLC and RA for example.
On the operational front we are again very similar, the Irish smashed out a few Telics, including the initial invasion in 2003. The Grenadiers will very shortly be deploying on their third tour of Afghanistan.
Ah ok now I get you! Yea that seems plausible to be fair. However what we've been told is that it's to give families more chance to settle in one place which is why we are doing guard mounts from Aldershot. But I do get your point about the drama. Our boys aren't exactly the shy retiring types.
