This can be done with randoms albeit annoying or with a friend through a private match. To boost this, simply get your friend to start taking the radio point, then when the circle fills up to the bottom of the middle of the symbol simply hold
to capture it. You have like a 2-3 second window to get this. You can do this as soon as the game starts, and you also have around 7 attempts to do this in.

This is an online achievement. This achievement is earned in the multiplayer mode ‘Control’. In this team based mode, teams fight for control of a radio (similar to ‘Headquarters’ in Call of Duty). When a team captures a radio, a circle starts to close, and once it is closed completely, that team gets one point. The radio then respawns in a different location. Once one team gets four points/captures or the 20 minute timer expires, the game is over.
To capture a radio, stand next to it and hold 
for two seconds. For this achievement, you must break the enemy capture with just a few seconds remaining, which means the circle must be almost fully complete. The image below shows about how much of the circle should be left before you need to break the capture. When there is at about that much of the circle left, the team not in control stands next to the radio and holds for two seconds to break the capture. If done correctly, the achievement will unlock. If there wasn’t enough time to break the capture and the original team captures the radio, just try again at the next location.
This can be unlocked in both public matches or in private matches with one other person (which is recommended).
