|---|
| Source measurement | — | The vehicle is armed with a launcher and two mine-clearing line charges . When launched, a rocket deploys a line charge by extending it out into a line that crosses the minefield. When detonated, the charge causes a shock wave that destroys or disables all the shells or mines in an area along the line charge with a width of 6 metres and length up to 90 metres. Thus a break in the minefield is created.[source]UR-77 Meteorit · Description; only the objects and conditions stated in this passage |
