As soon as the world discovers something new, which is popular among the majority of the population, after a while a special slang (jargon) appears, which is used by both users and specialists in this field. A similar fate has not passed the field of computer games, where the concentration of such expressions simply exceeds all reasonable proportions. After all, the use of abbreviated or simplified words here reaches the greatest significance in the world, and sometimes their understanding is very important. Since if you are a specialist in technical support, promotion, or even a developer, you must be fluent in this dry and concise language, which is able to convey the essence of what was said to the population or colleagues in a few expressions. And the briefly abandoned phrase “cd 250” would express everything they need to know.
Spread
Although similar phenomena are observed in any professional sphere of human activity, only game slang has gained such diversity. Uninitiated people can only be surprised and perplexed, listening to strange expressions, thinking what “cd”, “rush in the center” are, and trying to understand their sacred meaning. After all, there are a lot of computer and console games, and they all have their own model, which brings its own terms to life. Therefore, not every user can understand what a fan of the World of Tanks, Tundra, or other arcade would like to say. Of course, there are well-known expressions that intersect, but because of the complexity of building the speech structures of an experienced gamer, a beginner or an uninitiated does not have a chance to understand them. Moreover, game slang does not age, it is constantly expanding its base and absorbing new word forms. All these expressions are regularly used, which is why we get a chaotic stream of information that causes a stranger a lot of questions: "What is" cd "?", "What do the abbreviations" kk "and" kts "mean?" etc. While for others, this language is simple, familiar and sounds better than any music.

Principles
It is important to emphasize that the formation of jargon of players takes place according to unwritten rules, which contribute to the acceleration of communication. Therefore, all the expressions in it are short and concise, as if chopped off with an ax. In order to understand them, you need to penetrate the essence of the presentation and regularly replenish your vocabulary. Only in this way can one gain extensive knowledge about the slang of gamers. Although their relevance to non-specialists and inactive players remains in great doubt.
Examples
Let us examine in practice some popular phrases that can be heard in the gamer community. The question that sounds most often is, "What is cd?" The answer is very banal, because this phrase has migrated from "Dota" to almost all games where spells are used, there is a reload of any skills or abilities. It indicates the duration of the wait before reusing the perk or performing the action again. It was not possible to avoid the penetration of this slang expression into the "World of Tanks". Therefore, the answer to a somewhat naive question about what “cd” is in WOT will now not confuse anyone. It can be easily checked by visiting the official site of the World of Tanks project, where the duration of reloading of absolutely all the tools that are found in the game is indicated.
Use in WOT
However, do not assume that this is an exceptional parameter, which is of the greatest importance. Its influence is important, but not unlimited. An important role is played by the speed of movement of the combat vehicle, its accuracy and armor penetration. All these conditions form their own system in which they are interconnected. As a result, the disadvantages are compensated by the advantages, which forms the necessary balanced weight of each unit.
American and French technology
At the same time, the refinement of the loading time of the gun for tanks with a drum system for supplying shells occurs in a completely different way. And to understand what cd is in World of Tanks, for this class of equipment it is not as simple as it seems at first glance. After all, these combat vehicles have a specific feature, it was historically embedded in their design and was reflected in the game. They can fire on the enemy continuously, but only until the full cartridge is fired. In a battle, it looks like this: a French or American tank fires from four to six rounds at the enemy, and then it is removed for a long reload time (in terms of playing time, it takes from 30 seconds to a minute). Significant damage was inflicted to the enemy, but the attacking combat vehicle also departs for replenishment of the ammunition. Such a technique requires the user to closely monitor the situation, since in case of detection this tank will be defenseless and will not be able to repulse attackers.

Additions
Using this drawback builds on some aspects of team play. There is an addon showing cd of the enemy. Although it does not apply to prohibited modifications to the client program, Wargaming does not recommend using it because of possible interruptions in the connection between the server and the user. The consequences of such an intervention can be different - from reinstalling the client to losing control of your own account. After all, the code of the mod program may contain malicious viruses, so all actions are carried out by users of the game at their own peril and risk. As a result, for the desire to find out what cd is and how long it is, you can pay too high a price, which will lead to the loss of personal data or even more serious consequences.
