This is way more common than you think it is and again, not special.
I prepped multiple PDBs from 2012-2015 while at DIA and then again while on the JS/J2 staff. Delivering a segment of the PDB is indeed noteworthy, but again, not particularly rare or an indication that you're somehow especially great or special.
This is the reality of the IC ... things that SEEM special to you are boring regular everyday events for us. Few people in the DoD/IC are exceptional and I can promise you that this guy wasn't one of them
