 In addition to reducing the visible launch signature from the enemy, this enables the Javelin to be fired from inside structures with minimal preparation, which gives the Javelin advantages in urban fighting over the widely used AT4 (which has a large backblast area, although this is lessened in the AT4 CS).A large backblast area would seriously injure personnel if fired from inside an unprepared structure and may betray the location of the launch to enemy observers.The missile also has a greater range than the US ATGM it replaces, the M47 Dragon.
