The target is a T72 Russian main battle tank (about 45 tons of steel with a 125mm main gun), while the "Javelin" is a small, man-carried shoulder fired anti-tank weapon. The "Javelin" is not a bazooka that up to now was lucky to just blow a track off an enemy tank with a direct hit at close range. This weapon makes tanks obsolete.
