Given the following context:

The story involves two fictional countries, the peaceful Republic of Sardun and their aggressive neighbor Gamibia. Unable to defend themselves from a Gamibian incursion, Sardun sends Major Zara and General Byrne-White to ask the help of MegaForce – a secret army composed of international soldiers from throughout the western world, equipped with advanced weapons and vehicles. The MegaForce leader, Commander Ace Hunter, will lead a mission to destroy the Gamibian forces, which are led by his rival, and former military academy friend, Duke Gurerra.
While Hunter composes an elaborate battle plan to destroy Gurerra's forces, Zara tries out to become a member of MegaForce. As she executes the various tests, Hunter's feelings of affection toward her grow.  And while she passes the tests,  he is unable to allow her to participate in their raid, because her presence, as an outsider, would disrupt the trust and familiarity of his force.
Eventually, MegaForce successfully para-drops its attack vehicles into Gamibia and Hunter mounts his sneak attack against Gurerra's forces. Although they manage to destroy his base, Gurerra has set a trap for them at the team's only means of escape – a dry lake bed where the cargo planes will pick them up. Gurerra sends his tanks to secure the lake bed while Hunter comes up with a plan to attack Gurerra from behind by crossing over a mountain range the enemy tanks had turned their backs toward.

answer the following question:

What is the full name of the character who leads a force whose trust in him would be lessened by Zara's presence? 

Ace Hunter
