This is not a guide but rather an introduction to a like-minded community. Playing DAYZ on official server, this achievement is very hard to obtain even with friends to boost, let alone playing solo. You don't always spawn with your friend and it is a nightmare to try to find each other.
Currently, a community server is being operated temporary to help players get such achievements. The person running the server plans to have it up until 2 July 2020 (he may extend it). Search for the name: KawiNinjaRider7
under community server.

Players will spawn at the same location as others, this helps a lot.
If you are not there with your friend, you will eventually meet someone. Talk to them (press down button to talk) and they will most likely agree to help. They may even drop you a melee weapon or other materials to help you with this achievement or other achievements.
Don't forget to return the favor and be nice to other people. No Player vs Player allowed in this server.
