Just as a bit of trivia.
The Saviors have acquired M2 .50 caliber heavy machine guns.
It is a powerful weapon that will bring on a world of hurt to any target it fires on.
Unless the Saviors have military veterans who are familiar with the .50, AND have a head space and timing gauge, things will so south quick.
The barrel of a .50 is detachable. Therefore, one much check the "head space" before every firing to make sure the barrel is seated properly into the main part of the weapon.
One can only do this if you 1) know how to properly seat the barrel (not that hard), AND 2) check the seating with a head space and timing gauge.
Easy to check, but without the gauge it cannot be properly checked. If not checked, sooner or later--most likely sooner--the .50 will explode while firing, injuring or killing the operator.
As I said, a bit of trivia! And I doubt the producers even considered this.
