Here is a form I print and give to each player in my marine character campaign based on Aurore.

It is a "cafeteria plan" for weapons and equipment.  They just circle their desired weapon loadouts.

Some weights ( mass) are extrapolated from Twilight:2000, with a fudge factor for better tech ( lighter, stronger): kit, GL rounds, [can't remember what else].

The first mass column is for the sum of items on just that line ( 2 full one-liter canteens mass 2kg).

The second mass column is a subtotal for that group ( at the bottom of each group).

So I select:
armor and kit = 20.0kg
m4 and ammo   =  6.7kg
ammo for GL   =  2.7kg
               -------
I am carrying = 29.4kg

Note: if they activate their emergency beacon, their total sig is +2 sig ( the armors -2 sig doesn't make it sum to zero).
