I'm in the process of updating the USMC OOB for 2023 and while creating formations I found myself thinking about an order given to the North Koreans/Chinese during the Korean War (1950-1953).
"Do not attack the First Marine Division. Leave the yellowlegs alone."
Why yellowlegs?

With weapons disbursed down to the Company level (as was common) a full-strength USMC Rifle Company had the following:
170ish:  M1 Garand/M1 Carbine/M1 Thompson SMG
     9:  BAR
     6:  30cal MMG
     2:  30cal HMG
     2:  50cal HMG
     2:  Bazooka
     1:  75mm Recoilless
     3:  60mm Mortar
     4:  81mm Mortar (available from Battalion)
     2:  4.2in Mortar (available from Battalion)
     6:  105mm Howitzer (available from a Battery dedicated to Battalion)
I wouldn't want to attack this either!  That's a lot of machineguns and indirect fire support for a "mere" company.
