Forum:James Vega and Random Alliance Questions

I'm working on a fan project and for the sake of accuracy in dog tags, I have a few questions:

-What is James Vega's Middle initial? (if there is even a way of knowing)

-Say his dog tags had the alliance logo in the back, do you think his would be the spaceship with the three stars, or the logo on his t-shirt (the one with the added knife/sword and lightning bolts)? Or the logo with Earth instead of stars?

-Does his shirt say SP-03 or SF-03? (I think it's SF but I'm not sure)

-What do you think about this format for his dog tags:

VEGA, JAMES (though I think I might go with James Vega instead) SA:SF-03;N7 (Or should it be SA:N7;SF-03 or what?) O NEG
 * Random Number here*US

I tried to mesh different countries' way of doing dog tags... If anyone has better ideas, please let me know. -Threewine
