Back a few years ago, I used to play on a scenario paintball team in the old semi-pro SPPL league. My teammates gave me the call sign "Hawkeye" because I seemed to be decent at spotting the enemy. I soon transitioned into airsoft and online gaming and later changed it to "Hawker", since the action hero character, "Hawkeye", became more famous and people thought I was referencing that. This is the name I played with on the old THG server. Hippi and I were both admins there. They called us the Bonnie and Clyde of the server, lol. After a while, due to some bad decisions of the upper server management, THG started a downhill spiral, and we decided to start our own server in secret. It didn't feel honorable trying to take any of the server population with me so I decided on a fresh start and needed another name besides Hawker. I just pulled "Sandman", (a somewhat cliche allusion to being an assassin, if you will), out of the air as a temporary solution and it stuck.
