It's great fun from about 1700-0600. It starts by reporting for an earlycampo or seven, the better to prepare for a detailed reconnaissance of the target rich environment that is O'Donoghue's/Canterbury's, followed by launching a full scale assault on El Puerto at about 0100. The survivors then convene at 0530 at reporting point Victor for a Campo Gold to round off the evening.
Or at least it used to be like that, though I've heard it's gone fairly quiet in the last few years.
