RoundUp? A Weedkillser
VVHA,
The RN do have an equivalent of Op Round Up - your comments suggest that you haven't spent any time at Faslane. As a frequent light-blue visitor at HMNB Clyde 3-4 years ago, many was the time I received a 'shake' in my 'cabin' to check my id as teams of RM and MDP whizzed around the site in landrovers, responding to intruder alerts.
