Complete 6 countermissions challenge feels untested and discouraging

I’d like to report a serious issue with the counter-missions challenge.

I’ve played for around 10 hours, and during that time counter-missions appeared only 3 times.
Two of them were “destroy a tank”, which is highly situational and often impossible depending on the match.

I want to clarify that this is not a skill issue.
I consistently perform well and play objectives correctly, but player performance has no impact here.
The challenge is entirely RNG-based — you cannot influence mission spawns or types through gameplay.

As a result, the task feels frustrating rather than challenging and has significantly reduced my motivation to play both BR and regular modes.

Was this challenge actually tested in real gameplay conditions?
In its current state, it feels poorly balanced or not properly tested.

Please consider reviewing counter-mission spawn rates or challenge requirements.
