The robots will be bought, then stored in some base depot, cared for by civilian staff, and on 6 months' readiness. Once demanded by units it will be discovered that vital batteries don't comply with airfreight regulations/ EU recycling directives/toxic content/are no longer manufactured.
Field units may see one occassionally, usually in bits in the workshop, but a new trade/ specialist skill of robot operator will eat funds in arduous selection criteria, instructors who never touched the things before yesterday, and several committees of VSOs to design a new trade badge, to be supplied in various colours complete with regimental facing colours, camouflage, parade dress and mess dress varieties.
