Kill Death Ratio, or more commonly referred to as KDR, is a player statistic in online ranks and other ranking. It shows how many enemy (friendly kills do not count) players the player kills (on average) before dying. The higher the player's KDR, the deadlier they tend to be. Mission points and objectives do not change this. Professional Clans are more likely to demand higher kill/death ratios to achieve a deadly squad, usually 0.7 or above. One server only allows players with a certain amount of kill/death ratio range to enter ex: Foxtrot.

KDR is by no means an accurate measure of a player's skill. Low KDR's can be the result of team-killing or that the player is having a "bad day". Novice players that have low KDR's sometimes turn into deadly killing machines that have high KDR's a match, but are plagued by the deaths they had when they were a Noob.

To Calculate KDREdit

Take your total number of kills and divide by your total number of deaths.

Where k = total kills and d = total deaths

For example, a person with 18 kills and 7 deaths would have a KDR of 2.57, because 18 ÷ 7 = 2.57.

KDR UsageEdit

A player's KDR may also be used catch hackers. Usually a KDR between than 3.5 to 5 should arouse suspicion, but anything above that should be raising red flags. Although it is not abnormal for campers to have this high of a KDR. WARNING: A low rank with a KDR high then 3 might be a hacker be careful check to see if his HS ratio is higher than 50% that is a sign that a hacker might be in your game.

However, this is now all but useless ever since the mass KDR reset of January '11. Even players with a KDR higher than 5 could no longer be put under scrutiny or suspicion, leaving everyone as a possible suspect. Instead, players now turn to Fireteam Combos (especially DT), which cannot be reset and may easily prove that someone is a hacker in most circumstances.

TriviaEdit

• Papa is the only server in Combat Arms that does not affect your KDR. Therefore whoever plays in this server, their deaths/kills are not recorded (this includes Fireteam. A player's Fireteam combo does not appear in your KDR page).
• Foxtrot is the only server that has a required KDR to enter (1.0 or under).
• Most players judge each other by their KDRs. So if you have a low KDR, you would be considered a noob.
• Most clans needs a certain required KDR in order for a player to join.
