The 2000 reference is Sierra Leone, for which 7 Sqn was awarded a battle honour in the same announcement (correcting its previous omission). Afghanistan began in 2001: the clue is in the title of the honour 'Afghanistan 2001-2014'. 1(F), 3(F) and IV(AC) are all on the list; as far as I know there have been no Typhoon or Hawk T2 deployments to Afghanistan so I conclude that the Harrier sqns have been recognised. 800 NAS would not appear in a RAF list. For the Reaper sqns, both 39 and XIII are on the list. However I'm certain they would already have earned the honour by their actions as PR9 and GR4 units, respectively. A sqn can't be awarded a battle honour twice so the question of whether RPAS units can earn them hasn't been tested here.
