According to him, the documents, which are confiscated from the trespassers of the frontier, usually contain forgeries and erasures. The frontier guards are especially concerned about the fact that these methods are used by the people who "had to do with illegal armed units." Alexander Manilov reminded RIA Novosti that one of the main tasks of the frontier guards is "to prevent the crossing of the border by militants and terrorists who are involved in crimes both in Georgia, staying in the Pankisi Gorge, and in the territory of the Russian Federation within the bounds of Chechnya." The general said that "among the people who are trying to cross the frontier there are also mercenaries from different countries, including Arab states." Apart from that, said Alexander Manilov, all kinds of drugs, though in small quantities, were also detained at the Russian-Georgian border.
