Narrative:

I was put on a data side of a radar sector to help a person that was almost overwhelmed by traffic and complexity -- as I helped to coordinate and catch up. Conflict alert activated and the radar person vectored air carrier X and military Y to miss each other. The vector wasn't able to keep the required 5 mi separation. The radar display was hampered by data blocks over targets
