She is a very powerful unit versus The Infected and deals three different types of damage (, and ). While at higher ranks, she has a large health pool (unarmoured though), she is, nonetheless, vulnerable to piercing attacks. Despite the powerful attacks, this unit has a high Defense and Dodge value, which allows it to survive for some time on the front line.
An interesting point to note is that, unlike the Zombie hunter, she is capable of hitting air units with her second attack. Unlike many non-vehicular type of units, she is immune to the Plague and Poison, similar to Jedrek the Crusher.
At 69, it is debatable if players should get more than 2; hiring 1 seems reasonable to get by this boss strike in a smoother fashion but 2 is up to the player as this unit will only be effective against unarmoured units. She is fairly effective but players on a tight nano budget may skip this unit to save for the next promo unit.
Floyd? What are you maniacally cackling about? Have you created another highly contagious strain of "The Mondays"?
No Morgan! Far more exciting, I've been able to establish communications with our infected former fellow soldiers. What we thought were mindless killing machines are still thinking, feeling beings!
Oh, that's pretty neat, I guess. What are they saying?
Oh, uh, well… it seems that they are quite angry and, oh no. They want to kill all of us. They're challenging us to a massive battle.
This kind of thing seems to happen every year, so, this year I invited a "consultant" to the Outpost. She seems friendly, unless you're a zombie.
Finish mission
OK, so, she's scary and deadly. Ramsey? What's your professional opinion?
…
Ramsey! Stop drooling. She might take offense or mistake you for a zombie and lop your head off.

She's beautiful...
