Below are links as well as brief information on how to get achievements using savegames

   The save is stored along the path:

               steam\userdata\yoursteamid\55100\remote

  Before installing the profile from the manual, disable Steam Cloud and also save your profile so you                                                          can restore your game progress

                                            You can also download all saves in one archive

   I know that this achievement is not from the "EXPERT" series, but I decided to make it possible to quickly obtain this achievement. After installing the save, you will have a choice of how to get it quickly.
Option One - You can create your own server:
"Game Type Territory Control"
"Map - Any"
"Round Time - 2"
                                 "Score Limit - 100"
   After the start, we capture one control point - we get an achievement
Option Two - We go to any server where there are people, make 1 kill, our achievement!

There is also a possibility that when you install this achievement and turn on the game, you will already have the maximum level set to 75, which is why this achievement will not be counted towards you.

   To solve the problem with getting the achievement, you need to delete everything in the save folder, set the profile to level 49, turn off the Internet, start the game when you are in the main menu, connect the Internet, go to the single player game and return to the main menu until multiplayer is available , load the arsenal, you must be level 49.

   Farming this achievement with a partner or just playing on the server is not difficult, but we will not simply waste time on nonsense. Below is a link to the profiles. After installing the profile in the folder we need, go to the server, select the FIRST weapon layout and make ONE kill with the M4 and voila, our achievement!
                                                                                                                                                                                                          

   When installing this save, all you need to do is go to the server, select the FIRST weapon layout, then buy the "RQ-10 Parrot" drone for 350 BP (on button 5) and mark ONE enemy (You need to aim at the enemy and press the left mouse button)
                                                                                                                                                                                                                                                                                                                                                      

   With this achievement, it will be a little more difficult.
Firstly - transport is disabled on some servers, so you need to look for the server where it is enabled.
Secondly - the Transport that we need to quickly complete the achievement, namely the "Light Armored Vehicle" costs 1000 BP, do not spend points, but save up for this car, you need to make 4 kills, after which we buy this car when respawning and make ONE kill
   If you have a partner, it will be very easy to get this achievement

   The most difficult and time consuming achievement in the game, but the easiest one for you! Having installed this profile, select the first weapon layout and complete ONE kill with the ACR rifle, our achievement!
                                                                                                                                                                                                                                                                                                                                                                                                                              

   There is also a chance that the achievement will not be given when finishing the last kill, but there are two ways to solve this problem:

1. Disable Steam Cloud (Right click on the game - Properties - Uncheck Steam Cloud) Try to enable the game, the achievement should be valid.
   
   If the achievement is still not counted, go to the second method
   
   
2. In the main menu of the game turn off the Internet for a short period, and then turn it on again, after a while the achievement will be counted
