Splunk, once again, steps up to the plate to offer free training to veterans through their SplunkWork+ program. Visit SplunkWork+ | Veterans for more details. Biggest hurdle to signing up is the time required to verify your military service through TroopID.
I imagine taking the Splunk Fundamentals 1 training in concert with the free training offered to veterans would put you well on your way to a new career. The two won't get you to Splunk Certified Architect but it's good start.
