Guerrilla Ops are Missions in XCOM 2 that counter Dark Events. You will receive rewards for them if you pull them off successfully.
These random missions are counters to Dark Events. When a Dark Event occurs, the resistance will begin preparing a Guerrilla Ops counter which will alert you when available. They are the most numerous of the Side Missions that are available. Some possible rewards are Scientists, Engineers, Supplies, Intel or a new Soldier. Their objectives normally involve taking actions that disrupt ADVENT operations in a region such as destroying a relay or hacking an important tactical device. Successully completing the prepared Guerrilla Op will prevent the negative effect of the specified Dark Event from occuring.
Dark Events in XCOM 2 are Alien plots to either improve their equipment or attack the Avenger.

There is another Dark Event that I've encountered. It's called "High alert", I've only encountered it in "Impossible" where it might appear as "Hidden Event". It reduces the time you have for missions that start in concealment by 50%. I had a Dark VIP mission with a 4 turn clock. Needless to say, that is humanly not possible. I have a screenshot, just not certain where to put it.
