You will get dog-tags sooner or later, but I wouldn't be too concerned about them. You normally get red-fibre circular ones for peacetime, which you keep on your respirator (gas mask) haversack & metal engraved circular ones when you go operational. (Not like the rectangular US ones). You get two tags, name, rank service number, blood group. One on a large chain to go around your neck, the other one interlinked on a little chain, just big enough to go on your big toe if your head falls off.
(well, that's how it was explained to me when we were issued the stainless steel ones!)
