From d6 Space: Range: This factor takes into account that the weapon will be less effective the farther it is from the target. The values given are the maximums, in meters, for Short, Medium, and Long ranges. For generated values, roll the character’s Strength or lift. The modifier after “STR” indicates the number to take from or add onto the total. These totals, in meters, determines the ranges the character can throw the item. If the total becomes zero or less because of the modifier, then the character cannot throw the item to that range. (Gamemaster who prefer straight values should multiply the die code in Strength or lift by 4, then add the pips to get the “STR” value.)" So August Storm has a lift of 5D and a concussion grenade (range: Str-4, Str-3, Str +3). He rolls very well and a gets 20. So the short range is up to 16m, the medium range is out to 33m (16 plus 17), and long range is 56m (33 plus 23). If GM uses static number, it would be 20m (5 x 4) per range band (short would be 20m, medium would be 40m, and long would be 60m).
