How many dice may the defender roll?
The number of dice the defender can roll is explicitly different in different sets of rules. In most editions the defender rolls 1 die if he has 1 unit in the territory, and can choose to roll 1 or 2 if he has 2 or more units. Some sets of rules (New Zealand and U.K. circa 1990) state that the defender can only roll 1 die unless he has at least 3 units, which weakens the defender. It also removes the interesting decision an attacker has when he doesn’t actually want to take a territory but is happy just to reduce it to 1 army (when you get to the redeployment rules you’ll see why that might be) since he no longer needs to worry about reducing the defender from 2 to 0 in one throw. I have on occasion rolled just one die as the attacker because the defender only had 2 units left. Some versions of Risk from other countries (such as the Brazilian War! or the Italian Risiko!) allow the defender to roll as many as three dice.
