Ahoy, Bubblehead1980...
From what I have gathered, what they were eating on, if I am NOT mistaken was basically what we now know of... as Spam.
No,
not that scummy crud you get in your email box... but canned meat.
That they were even trying to eat it, at that point, means that obviously they had been out there for some time & were still expected to cover their assigned area.
Of course, that's just a basic stab in the dark guess.. but, am fairly confident on that being what it was... just their own version of that meaty treat.
