A few years ago an RM major, who was killed in the Gulf, had the child by his girlfriend accepted as being NofK and something similar happened to Trooper Bradley Tinnion an SAS soldier killed by the West Side Boys, whose G/F was pregnant.
At one stage if my wife (then sqn ldr WRAF) had died in service I would not have received any rights to her service pension but if the reverse was the case, she would have had mine. Before that there was a rather confusing business of the 1/3rd pension and I paid into a fund for a 1/2 rate widows pension, only for the law to change after I'd shelled out a goodly sum.
