This has been translated from the original russian.  Some freedom was
evidently taken in doing so to make it more understandable.

A line of Russian soldiers stands in front of a huge rectangular hole in the
ground.  Sergant commands:
                  -  "Private Ivanov!"
                  -  "Yes, sir."
                  -  "Stand like this:"

                          O
                         _|______
                        | |
                        | |
                        | |
                         | |
                         | |
                         | |
                         | |
                  -"Jump!!"

The soldier jumps  into  the  hole.
The sergant  commands again:
                     -  "Private  Pyetrov!!"
                     -  "Yes, sir!"
                     -  "Stand like this:"

                       |
                       |  O
                       \ -|-|
                          | |
                          | |
                          \-\
                           | |
                           | |
                           | |
                       -  "Yes, sir!"
                       -  "Jump!"

  The soldier jumps and falls into the  hole.
  The sergant commands  again:
                        -  "Private Sidorov!!"
                        -  "Yes, sir!"
                        _  "Stand  like  this:"

                             O
                           |-|-|
                           | | |
                           | | |
                           | | |
                            | |
                            | |
                            | |
                            | |
                          -"  Yes,  sir!"

     At  this point a car with a colonel arrives to that place.  Colonel,
very angry, comes up to the sergant and tells him: "Comrad sergant, how many
times do I have to tell you: STOP PLAYING TETRIS WITH THE SOLDIERS!!!!!!!!!"
