Ah, that brings back memories. It was after we got our own "private"
imps at BRL.
The BRL hosts of the day had the name BRL-XNNN where the X was the name
of the division
V - Vulnerability/Lethality Division
S - Systems Engineering and Concepts Analysis Division
T - Terminal Ballistics Division
I - Interior Ballistics Division
L - Launch and Flight Division.
B appears becvaues SECAD was the Ballistic Modelling Division earlier.
Mike wanted to callel BRL-SEM (the SECAD Experimental Machine) BRL-SEX
originally.
Jake Fienler at the NIC refused to accept it.
