There is definitely such a job. In the mid-90s between university semesters I did temporary work in SW London. One company I worked at for a few weeks was called Adpax - they specialised in making packaging, particularly for munitions. I just had to put washers in small plastic bags, or detonators into boxes. In the larger building next door I saw them making enormous boxes to fit all kinds of stuff - including what looked like missile parts. I did a brief stint in that building, can't quite remember what exactly I did except wear a mask and wield a glue gun. Felt quite heady at the end of the shifts. This is the only trace I can find online of them: https://web.archive.org/web/20041127024643/www.adpax.co.uk/mod_page.htm https://web.archive.org/web/20041127024643/www.adpax.co.uk/m...
