  2. ExtremaRatio - 185° RAO - 2018 Version - heavy folding knife

    New version 2018 with improved grip: uses the same handle as the RAO II model

    Folding knife made to specific requests of the Italian Army department 185 ° RAO (Regiment Acquisition Objectives) and currently supplied to the homonymous department. The supplied knife differs from the civil one only because of the total lack of writing or logos on the blade.

    HISTORICAL SUMS ON THE DEPARTMENT:
    The 185 ° RAO of the '' Folgore '' is a department with an ancient tradition, but very new. In fact, it was born on April 3, 2000 following the reconfiguration of the 185th terrestrial paratroop artillery regiment. Based in Livorno, it is an atypical department of the artillery weapon, currently inserted in the Special Forces basin.

    Entirely composed of voluntary personnel, the 185th RAO selects its components through the passing of a physical test and a qualification course on modules '' with increasing difficulty ''. The tasks entrusted to the RAO's men are many, but all very delicate: it is about gathering information on enemy objectives and 'passing them' to one's command. More generally, it can talk about '' recognition in sensitive areas ''. '' It is therefore evident - they stress to the Army - that the activity of the acquirer takes place mainly in hostile territory, in small self-sufficient nuclei that act in isolation ''.

    RAO paratroopers are specialists in '' infiltration and exfiltration '' techniques and are able to move in the operating area '' for up to 8-10 days without external supplies ''. They know how to 'escape from capture, escape and escape from an' enemy controlled area '' and, above all, as '' identify, determine and evaluate objectives '' of strategic interest. Since 2002, the year of reconfiguration, the 185th Regiment detachments have operated in all the hottest operational theaters: from the Balkans to Afghanistan, to Iraq. Here they mainly carry out surveys for medium and long-range information purposes and for monitoring the area of ​​responsibility of the Italian contingent.
