HESCO is most like a fortification in game terms, so I would use an appropriate bunker icon that allows 360 degree firing (ie has an invisible MG turret like some of the MG bunkers?) and place some dragon teeth, mines or barbed wire around it perhaps.

Or use a hollow square of a few stone buildings similarly surrounded by dragon teeth etc as the buildings will stop direct fire into the hollow square in the middle of "camp"?. Leave a gap as the camp gate, or put a single building back a hex as the guardhouse to allow vehicular driving in/out the "entry" whilst stopping direct shots into the courtyard of your "Fort Laramie".
