This weapon shoots like a normal shot, however it will scan the area around it's arc for players. If the white line hits an enemy, it will lock a green ball onto them, which will explode after a few seconds.
The white line that scans the area will always start pointing upward and turns clockwise when scanning.
In real life, radar, sonar and lidar are effectively the same thing. The difference between them is what they use. Radar uses radio waves, sonar uses sound waves, and lidar uses laser light.
The Sonar will appear to tag enemies outside its range. This is because it uses the same graphic as Radar but has the range of Lidar.
The total damage this weapon does is exponential against stacked enemies, modelling a parabola. This is because the weapon plants bombs on every tank it scans with their own individual AoE. If seven enemies are stacked it will plant seven bombs which explode all seven tanks seven times dealing 49 times its normal damage. An equation to model this weapon's damage, where t is the number of tanks stacked on top of each other, b is the base damage, and d is the total damage; d = bt 2.
