One word? CRAPITA. Their involvement in HM forces recruitment has been ghastly.
My son began the recruitment process in September 21, he starts at Pirbright in September 22. No hiccups, fails or medical issues, it just takes that long apparently.
Ten years ago I joined the Army Reserve after leaving regular service two years previously, despite having all my information already in the system it took me seven months to get back into a green skin. Thanks to CRAPITA.
