Automatic fire and Grenades

[kcdusk]

I thought there'd been some threads on this in the past, I've done some searches but couldnt find the Q&As i was after. Sorry if the questions seem repetitive, both situations are something i'm looking to firm up and get some consistency for my own game rules.

1. How do you handle automatic fire against targets?
Under V2.2 if a weapon has a ROF of 5, then it can fire 5 bursts of 5 bullets each for a total of 25 rounds. Do you roll 25 to hit dice? Do you roll to hit 5 times and adjust the damage for hits? Are you rolling for each person in the "danger zone corridor"?

2. How do you handle hand grenades?
Does the player nominate a target point, then roll to hit?
Hit or miss (after determining where the grenade lands) how do you determine damage? Knockdown? Stun? Anything else?

Happy to hear your interpretations of the rules or your house rules on these things.
