Actually I got this title after finishing quest Northern Wheat Plantation of Calpheon, you don't need to do Supporting the Hostage Rescue Force which the next quest in chain.

this website says:
"
1. Obtain by completing '[Boss] The Stomp Heard Round the World'
2. (Main Quest before renewal) Complete 'Clear Justification' before talking to Karcenov.
"

but i searched everywhere and no luck :'(
