Anti-frogman Techniques - Risks and Threats To Be Defended Against

Risks and Threats To Be Defended Against

In World War II this need for military underwater security was first shown by the achievements of frogmen against armed forces facilities: see for example Italian frogman actions in WWII. Since the late 1950s, the increasing demand for and availability of sophisticated scuba diving equipment has also created concerns about protecting valuable underwater archaeology sites and shellfish fishing stocks.

The 12 October 2000 USS Cole bombing was not carried out by underwater divers, but did bring renewed attention to the vulnerability they present for naval ships. Divers can swim 100 to 200 yards in three minutes time, and large sonar ranges would need to be established around ships in order for security forces to detect underwater swimmers in time to make a sufficient response.

In March 2005 the Philippine military, interrogating a captured anti-government terrorist bomber, found that two of Southeast Asia’s most dangerous terrorist organizations linked to Al Qaeda were said to be jointly training militants in scuba diving for attacks at sea.

Famous quotes containing the words defended against, risks, threats and/or defended:

    Man is exceedingly well defended against himself, against being scouted out and besieged by himself, and he is usually able to make out no more of himself than his outer fortifications. The actual fortress is inaccessible to him, even invisible, unless his friends and enemies turn traitor to him and lead him there by secret paths.
    Friedrich Nietzsche (1844–1900)

    There are risks which are not acceptable: the destruction of humanity is one of them.
    Friedrich Dürrenmatt (1921–1990)

    Among the best traitors Ireland has ever had, Mother Church ranks at the very top, a massive obstacle in the path to equality and freedom. She has been a force for conservatism, not on the basis of preserving Catholic doctrine or preventing the corruption of her children, but simply to ward off threats to her own security and influence.
    Bernadette Devlin (b. 1947)

    I have the greatest aversion to being a candidate on a ticket with a man whose record as an upright public man is to be in question—to be defended from the beginning to the end.
    Rutherford Birchard Hayes (1822–1893)
