just a few things that just rub the wrong way.
This is coming from my point of view as a Retired Marine.
1. When narrators screw up Military terms and names of gear. examples; MOLLE it is pronounced as MAUL-EE not mol- lay.
when saying names of weapons or vehicles
military personnel say MRAP like it spelt as a word not M R A P as in separate letters. that goes for all vehicles just as when some one says HMMWV as humvee. when it comes to numbers on weapons or ammunition the number is said as a whole number not individual numbers ie M240G machine gun is said as MtwofortynineGolf. with ammunition 5.56mm is not said 5 point 5 6 its five five six or seven six two.
last thing FOB is not said as F O B its pronounced as spelled FOB ( fahhb ).
Basically if you are writing or Narrating any type of military terms research ow the military actually says it, it will immerse the reader or listener more in the story.
Interesting take on the Zombie/virus pandemic genre.
