What is the name of Cobra’s front company? I'm not asking about Extensive Enterprises. The one I'm asking about starts with, I believe, an "A"

Thanks.

ARBCO is the main one.

It's not the only one. Broca Brothers something was used once, another anagram of COBRA, also used for Fred Broca and Broca Beach.

There was the Cryptic Order of Benevolent Reptillian Apostates, a fake fraternity hall located in Broca Beach.
