As it is written in one famous poem: In war, without a joke, it’s bad, If you’re depressed, it’s a disaster! A warrior shouldn’t groan, Humor will always help! The book by the head of the 1st department of the Department for Combating Terrorism of the FSB of Russia A. Platonov in its sparkling humor is comparable to the immortal the creation of Alexander Tvardovsky “Vasily Terkin”. It’s not for nothing that another name for the famous poem is “The Book about a Fighter.” And the heroes of A. M. Platonov’s book are fighters of the invisible front, although they do not act in war, but, as they say, “in conditions close to combat”: at border outposts of the Far East, on the Kuril Islands, on foreign “business trips.” These are security officers, on whose shoulders is entrusted the heavy responsibility of protecting the peaceful tranquility of our Motherland. They, like no one else, need to “relax” after a battle with a glass of “tea”, sit down, joke - sharply, but kindly. It happens that a stern law enforcement officer finds himself in a funny situation. The author has collected, as he himself writes, many “funny, tricky and amusingly instructive stories from the life of security and border service officers,” which he offers to the reader. Not only to have fun, but also to learn a life lesson from every joke.
