Does anyone know what the E Squadron is? From what I know, it's not a branch of the UKSF, but more sort of a Special Forces Operations unit for SIS(MI-6), and is made up out of elite hardened veteran British SAS, SBS and SRR soldiers. So this much I know, but are these soldiers selected, is there a selection process they must go through or even further training? And what sort of missions do they carry out? Obviously all their missions would be in the best interests of SIS, but what exactly are the jobs they would do? Do they ever do solo missions? I understand there is very little imformation on them, but surely somebody can shed some light on the matter.
