Story[]
The UTS-15 was in the service of the InGen Security Division by 2015.
Its most notable use was during the Isla Nublar Incident of 2015 where it was used by Asset Containment Unit member Miller when he and his team were hunting the escaped Indominus rex. The shotgun unfortunately had absolutely no effect on the creature and Miller was subsequently eaten whole.[1]
