Probably because he's usually the first to charge to the rescue when someone 
is in trouble.  Which doesn't necessarily mean he always succeeds/should get 
credit, but sometimes he should, per my pov.  Also, a lot depends on how you 
count a rescue.  Is it a rescue if the person/persons to be rescued are in 
danger but not actually prisoners?
Off the top of my head and probably forgetting some of Tarrant's 
charges/rescues:
Powerplay: Death Squad trooper about to blast Avon into oblivion; Tarrant 
saves him.  And one might count Tarrant's timely intervention when he knocked 
Avon unconscious and prevented Klegg from identifying Avon, but I'm not sure 
Avon would count it.  He'd probably feel Tarrant should have come up with a 
less personally painful-to-him intervention. :)
Volcano: Tarrant and Dayna rescue Cally.  One could argue which of them 
should get credit, but I'd allot it equally.  Tarrant makes the decision that 
they *should* attempt the rescue (Dayna might possibly have declined if on 
her own).  Then Tarrant gets shot and it's Dayna who takes out the troopers 
with grenades.
Dawn: Tarrant charges out to rescue Vila's "body."  Tarrant "rescues" Orac by 
providing a cleverly deceptive description.
City: Retrieving Vila is a group effort, but it's Tarrant who insists they 
are going to stay and wait for him when Avon wants to leave.
Children: Tarrant's the lead voice in the let's go rescue Auron faction.
Rumours: Dayna and Tarrant pluck Avon from the Federation cell.  They want to 
pop back down to the palace to rescue him later, but Avon returns before the 
teleport coordinates are reset.
Ultraworld: Tarrant is the first to voice "let's go rescue Cally."  Dayna and 
Tarrant rescue Cally and Avon; again, I see credit going to both of them.  
Tarrant's explorations keep him and Dayna from getting caught with Avon.  
Tarrant's explorations allow him to know what to do to restore Cally and 
Avon's minds.  Dayna uses the explosive to break the two of them out of 
captivity.  Both Dayna and Tarrant free Avon and Cally before they are fed to 
the Core.
Moloch: Tarrant and Vila: team effort to rescue Dayna and Avon. 
Death-Watch: Team effort, with Tarrant playing key role, when they "rescue" 
Teal and Vandor from the Federation.
Terminal: Cally and Tarrant charge down to protect Avon's back.
I could continue through fourth season, but I think the above paints enough 
of a picture to answer the question.
