What happens after you earn 2015 service medal CSGO

You can receive one weapon drop per week. You will receive this drop the first time you increase your Rank during the week. Your level progress bar will indicate when you are eligible for an earned weapon. so the more you play, there will be more chance to get random drops but you will sure get one weapon drop per week when you will increase your rank.

For more details on this please read the operation information page.

There was an update in CS:GO, which introduced levels in the game, now what these levels are for is pretty much to restrict people from playing MM (MatchMaking) right from the get-go ( pretty much buying the game and playing MM) this way, it would reduce the ammount of "noobs" you would catch in MM, now, to play MM you need to have level 2.

How do you get level 2?

You play, Casual, Arms Race, DeathMatch, even some community servers provide XP, all you have to do is get level 2, this way they can at least "force" the player to know something about the game before playing MM.

When you first start playing you need 10 MM games before a rank is given to you, while you do not have this rank, unless you are in a full lobby (5 people, including you) you will not be able to play with ranks higher than MG1 (Master Guardian 1) the rank insignia is a single AK47.

Remember that if you play with your LEM (Legendary Eagle Master) and DMG (Distinguished Master Guardian) friends, you will have a hard time playing properly (unless you secretly are a csgo pro) since they will be high above your skill cap, which might cause your rank to inflate and make you lose a lot of upcoming games when you play solo, so i suggest, play alone your first 10 games, then play with your friends, after you get a rank.

To answer your question:

1. You need level 2 to play MM (Level that you get playing Casual and Other games modes).
2. You need 10 MM wins before you get a rank.
3. Don't play with your High Rank friends, you will just drop down when you start playing alone and get de-motivated to continue playing (I know this from personal experience).
