During my time as a Royal Navy operator, the highest importance that could be attached to any signal was a Z priority, which meant that it was a Flash message and anything else you were doing had to be dropped and the signal transmitted immediately.
Flash messages were usually enemy reports that would give information of what the target was, where it was sighted, when it was sighted and in which direction the enemy was travelling.
Well on a previous site, we had a page devoted to Flash information where links to where an internet activity action could be taken and on the insistence of the Elite Commander, we have decided now to create a similar page on this site. You will find it on the right. Visit it often and please help make it work.
