"My two cents on that particular challenge:
1. Level up a sniper rifle until you unlock the range finder.
2. Bind the range finder zeroing action to a familiar keybind/button, like the same one you use for holding your breath/focus
3. Go to Multiplayer/Custom Search and select Breakthrough and Blackwell Fields only. This is the best combo. If you get bored, you can add more maps like Mirak Valley and Operation Sandstorm.
4. Climb up a hill and look for other snipers doing the same challenge. Take your shot, go prone (so the hill serves you as cover), stand up, and repeat."

YES! EXACTLY! (I'm PS5 BTW)
Although I mainly play as an Engineer tank driver (I'm an armor plated sniper in a tank) but I also like Recon and pieced enough info together to do the same thing that he is suggesting here!
I have Battle Pass (free when I purchased the Phantom Edition for $99) and I have unlocked a wonderful weapon:
An SV-98 called "Long Memory," (reminds me of my Kar-98 sniper rifle in Battlefield 5) and comes with the works! Eight-power scope, rangefinder, a stubby, mag catch, match grade long-range ammo, (eventually I will trade the stubby and the mag catch for the ADS Bolt), etc. A great weapon! So, I took that weapon out with my Recon guy and started popping off those long distance headshots and winning the battle when another sniper saw me and we had a shootout.. like the Wild West ... and usually I won.
Bind the Range Finder and your Steady Scope and your Zoom to the SAME key or button, point your weapon at a target and it will instantly lock onto the range. Aim slightly below the "Dorito" whether you can see the enemy or not, and pull the trigger. LOVELY! Done and done.
