Rosie's history is something of a mystery. We have managed to discover her identification from serial numbers on her interior and through that her service record. Rosie was a Mark 6 Scout Walker and has been refitted three times to current AT-ST standards (the Mark 9's are very similar in appearance to the classic Mark 7's). Rosie fought in a variety of major and minor campaigns for the largest (but easiest to get in to) Army-for-Hire unit of Scout Walkers and was decorated 9 times. At some point - for reasons unknown - Rosie went AWOL from her unit and nothing was known of her until 1997 when she was discovered covered in rubbish in a back alley in London, off her head on FUEL.
				FUEL addicts are relatively common on Earth, and Rosie was discovered by one of the few FUEL out-reach programs operating in this system. Rosie was cleaned up physically and rehabilitated through a series of vigourous code-tidy software routines, although the FUEL had already damaged much of her memory beyond the possibility of reconstruction. Once she was back to reality we approached the rehab group and herself with the idea of partnering up with Jim on the Scout Walker Kama Sutra: Rosie, being a deserter, would have trouble finding gainful employment in AT-ST mercenary groups if she even wanted to return (having gone AWOL she presumed she had once upon a time had a good reason not to want to return). The Scout Walker Kama Sutra was an opportunity for Rosie to modelling career, and were are very lucky she chose us from amongst the range of options that were available to her.
