Interested in how scoring works in HLL, here is the results of testing in game by the HLL Training Camp. A few specific highlights specific for update 8:
Satchel charges earn 5 points per item destroyed, even if that item gives zero points for destroying it by hand
Truck drivers get 30 support points/min behind the wheel
Zero points for supply trucks dropping supplies, 1 support point per supply consumed with those dropped supplies.
AT/Engineers get varying support points for placing down blue prints. ANYBODY that does any % gets full credit for built towards their support points.

Testing/Validation Team:
