Military slang. Roughly: "to get fucked" or "fuck you." Also: "Fuck it."
Origin: 35th Infantry Division (
Kansas) National Guard deployed for the first
time since WWII. The "Santa
Fe" Division, named for the Santa Fe Trail that settlers followed across
Kansas from the Eastern USA to New Mexico, immediately began to break down relationships across Central Command and generally treat the subordinate units with derision. Since then Guard, Reserve, and Active Duty units which were under the Division's command have used the motto in this way.

LT
John - Nothing I can do about it. Santa Fe, I guess...
