Post OP

Post Op is a shipping company in Grand Theft Auto IV and Grand Theft Auto V, and is a parody of the United Parcel Service. Though it is not featured in any missions, its trucks, which are mainly Bensons, can be found in many places. The name is a sly-reference to a post-operation transsexual, further evidenced by the slogan "No Longer Just Mail".

In GTA V, the company vehicles are Mule and the Benson, which both can be found in Los Santos.

Trivia

 * Post Op's name is a reference to sexual realignment surgery, whilst also being a play on the fact the company is a postal business.
 * The company's possible rivals are Liberty State Delivery and Alpha Mail. They all use a different type of truck (LSD = Yankee, Alpha Mail = Mule, Post Op = Benson).
 * Mailmen for the company can be seen but are rare.
