Here's the PETA letter to Gen. David H. Berger, Commandant of the Marine Corps:

It's every bit as stupid as all the clone articles that can be found about this make it out to be. PETA seems to have ignored the parts of the video both talking about and showing the trainers teaching the marines about edible plants and fruits, and the marines eating some of those plants. It makes an argument based on the false equivalence that because SERE specialists use certain VR training sims as part of training - for pilots, NOT Marines - in safely bailing out, parachuting, landing, etc... the stuff that pilots need to know BEFORE they incorporate their very similar real-life survival training, so that surely Marines could just do the same, plus add some off-the-shelf video games with "food procurement components," whatever the fuck that nebulous description could possibly mean to encompass in any military training-incorporable way.

SERE specialists are already using virtual reality to prepare Air Force pilots for worst-case scenarios, and interactive video games that have food procurement components are now on the market.

These disingenuous motherfuckers at PETA should take their prescribed VR and video game survival training, then get dropped in the middle of Cambodia with the same kit Marines get for their survival trials and see how quickly their keyboard warrior brand of "training" gets their asses dropped by any one of the things the Marines in the video were eating/drinking.
