Ask whoever you are deploying with (as above), if you want to put it on tinternet (youtube etc) then it is supposed to be cleared through Media Ops this mainly due to OPSEC, PERSEC, protecting TTPs etc. Alledgedly whatever you record is Crown Copyright as they are paying for you to be there although I reckon this is but a rumour.
Ask in advance "out of interest" is your best bet.
But very difficult to enforce.
Listen to OTAG or your RSOI FFS, they have the latest persec gen.
Just go on youtube and look for paras/ marines* fighting taliban to see why your not allowed to post film of what your bases look like, especially with all the info that is embedded in film/ photos these days.
*Other units with poor persec on early Herricks are available.
Go and get your Media Ops rep, normally an attached junior Officer who has been epicly dicked in the BG, and he should forward any material to Meeja Ops, higher i.e. Lash or Bastion (who are allowed to clear stuff, normally viewed on fast forward). AFAIR Media Officer isn't allowed to clear his own blogs!
