As a Cavalry Scout deployed in a combat zone. What is required to receive the Gold Spur award?

Spurs are not a recognized Army Award. It’s a unit program. It works however the senior commander says it works. They usually have an SOP. If there was no unit spur program and the unit is gone, I don’t see a way unless another Cavalry unit brings you in under theirs.

Gold Spurs Buddy. Here's an extract for the 19D Cavalry Scout files section:

"I've been noticing a lot of bickering about which type of 'Spurs' were higher. Here's something that was worked out in the early 1990s.
.
The Order of the Spur is a Cavalry tradition within the United States Army.
.
The Spur Hierarchy in order of precedence determined by various Cavalry CSMs around 1990 was as follows
1. Combat Spurs - Gold (actually brass for enlisted Dragoon/Cavalry Revolutionary War) Officers and enlisted must have served assigned or attached in combat with Cavalry or Scout/Recon element.
.
2. Cold War Spurs - Bronze (some units Silver) (since 1945 - 1990 but not by all units). The earlier era ‘Spur Ride’ utilized the concept of Cavalry units, Scout Platoons (like with Infantry or Armor BNs) deployed on the East-West German Border, the Korean DMZ or the Panama Canal Zone. The Stateside Cavalry units and Scout/Recon elements that deployed overseas to Europe, Japan/Korea or Panama large scale exercises in support of the Army mission were included. Soldiers had to receive MOS performance pay (prior to 1970s) or pass 80%+ (late 1970s) on their SQT/Common Core Tests, + receive a distinguished with their Scout team/squad/section's Scout Proficiency Course (SSPC) or their crew's tank, Sheridan, Artillery, Anti-tank, ADA etc gunnery. Though called Spur Rides their criteria and implementation of the practice was based on an extended, longer-time term Qualification Ethos which was in performance of their duties. Often this process took between 6 to 15 months. That time window is based on I saw two guys make it 6 months and never knew of but one (he got injured) taking till 15 months.
NOTE1: The Cold War Spurs have in some units been adapted to what is now called "Deployment Spurs". These are awarded for Overseas Deployments where there isn't Combat but are in support of exercises in foreign countries such as Poland. and Korea's 'Team Spirit' and Thailand's 'Cobra Gold'.
.
3. Rider Spurs - Silver (started up in some stateside units about 1980). The later era or Post-Cold War Spur Ride was developed to carry on the Order of the Spur tradition. The modern ‘Spur Ride’ varies from unit to unit, but it is generally an event held over multiple days during which a Trooper must pass a series of physical and mental tests relevant to the Cavalry, detached/attached (such as with an Infantry HQs) Scout/Recon platoon . Some of the tests evaluate leadership, technical and tactical proficiency, physical fitness, the ability to operate as part of a team under high levels of stress and fatigue under both day and night conditions, though the specific tests vary by unit. A written test is often also administered, with questions that cover United States Cavalry and unit history.
NOTE2: Some units award participants in the Cavalry's Best Scout Competition the Rider Spurs if they have not already earned them..
.
That's pretty much 'The Hierarchy' and it's based on some pretty practical precepts - Combat thumps all, Risk to Life is second (the West German Border and Korean DMZ had many skirmishes) and a demonstration (though grueling - not life threatening) of the Trooper's performance is lowest.
.
I hope this helps."

Totally dependent on your chain of command. For me, it was 3-months in Iraq to get awarded gold spurs.
