== Biography ==
=== Early military career ===
Around 2525, then-Second Lieutenant Silva was assigned to command a platoon of Marine Shock Troops aboard the UNSC Atlas.
On April 22 of that year, to test the new SPARTAN-II physical augmentations, ONI enlisted four of Silva's men to confront John-117 in the Atlas' gym. The ODSTs were no match for the Spartan, and two were killed while the other two were severely wounded. Silva was debriefed by an ONI officer, declaring angrily that the Office were "damn monsters" for sanctioning the training and deployment of child soldiers and the experimentation thereon. Stating that the Spartan-IIs were victims of ONI's desire for a "terror weapon" and proclaiming solidarity with them. He later met with Lieutenant Catherine Halsey, who thanked him sincerely for taking a stand against ONI's view of the Spartans as simple "assets" rather than human beings and apologised for what had happened to his men.
=== Battle of Hat Yai ===
By 2528, Silva was a member of the unit led by Major Sedavian, leading to his first close encounter with the alien Covenant on Hat Yai.
