Policing in Greater London, with the exception of the City of London, is provided by the Metropolitan Police Service, overseen by the Mayor through the Mayor's Office for Policing and Crime (MOPAC). The City of London has its own police force – the City of London Police. The British Transport Police are responsible for police services on National Rail, London Underground, Docklands Light Railway and Tramlink services. A fourth police force in London, the Ministry of Defence Police, do not generally become involved with policing the general public.

Ah, so.. The British Transport Police

Bermuda was discovered in 1503 by Spanish explorer Juan de Bermúdez. It is mentioned in Legatio Babylonica, published in 1511 by historian Pedro Mártir de Anglería, and was also included on Spanish charts of that year. Both Spanish and Portuguese ships used the islands as a replenishment spot to take on fresh meat and water. Legends arose of spirits and devils, now thought to have stemmed from the calls of raucous birds (most likely the Bermuda petrel, or Cahow) and the loud noise heard at night from wild hogs. Combined with the frequent storm-wracked conditions and the dangerous reefs, the archipelago became known as the Isle of Devils. Neither Spain nor Portugal tried to settle it.

During this period, Roman soldiers seem to have been modelled after those of the Etruscans to the north, who themselves seem to have copied their style of warfare from the Greeks. Traditionally, the introduction of the phalanx formation into the Roman army is ascribed to the city's penultimate king, Servius Tullius (ruled 578 to 534 BC). According to Livy and Dionysius of Halicarnassus, the front rank was composed of the wealthiest citizens, who were able to purchase the best equipment. Each subsequent rank consisted of those with less wealth and poorer equipment than the one before it.
