Buy Army Rations

This British army ration pack are safe to eat?
I know nothing about ration packs but I bought a surplus of an army . speichern He says it on "06/06" I suppose this is June 2006. If the contents are safe to eat?
On that day it was packed, no Expiry date, so it should be safe would be. Given how tasty you'll find it to be is another matter.
