A little humor, or fodder for NPCs
 

https://taskandpurpose.com/7-guys-yo...xmB2buGjDdPBBE Seven guys you meet in every infantry platoon

I would like to add

Shinny Kit: All of this guys kit is so new it looks like he just got form supply

Gear head: You need it he got it. He usually taking about some great new item or kit that he purchased

Crap Game - Anything you need this know someone who know someone who can get it for you for a price. In Theater this guy lives like a king

Mouthbreather - Nuff Said

and The Knife Guy (video)

And on the British side
 

I am familiar with the concept, but had not heard the word "ally" used in this fashion until today: http://www.craigrobertdouglas.co.uk/...ary-ally-ness/

Don't forget the shammer, also known as the ghoster. Never around when there's work to be done, always ends up near the back during a patrol, does almost nothing in the field but somehow gets all the awards.
