Apparently, America’s future engineers need to learn focusing skills, because they stepped away from their studies to answer forum questions about walrus ballistics. One engineer calculated an approximate speed for a walrus to stop the M1 while another figured out how fast it would need to fly to kill a T-72, in a thread on the website 4chan.
The calculated speeds are essentially the same: 292 meters per second for the M1 and 291 meters per second for the T-72, respectively. To get the walrus to strike the target at those velocities, it would need to be fired at supersonic speeds.
Check out their math below. Engineering students, feel free to fill our Facebook with your own calculations for anti-tank walruses, anti-aircraft bullfrogs, and anti-submarine lemurs.
