A 100m (330ft) long military helicopter has been drawn on a Devon beach to highlight the dangers of armed forces sites that are shared with the public.
The Chinook has been drawn on Saunton Sands beach, near Braunton.
The Ministry of Defence (MoD) said it was urging holidaymakers and locals to check firing and training times on any of its UK sites they can access.
People could encounter training, live firing, unexploded ordnance and fast-moving military vehicles, it warned.
The MoD's Defence Infrastructure Organisation (DIO) said its Respect the Range campaign was highlighting a number of sites with shared public access, including its Braunton Burrows training estate next to Saunton Sands.
It said there were "very real risks they face when entering shared land used by the MOD for training", including a number of popular coastal locations.
Other sites being highlighted include:
- Aldershot, Hampshire
- Barry Buddon, Carnoustie, Scotland
- Donna Nook, Lincolnshire
- Holbeach, Lincolnshire
- Lulworth, Dorset
- Lydd and Hythe, Kent
- Salisbury Plain, Wiltshire
It said precautions people could take included checking military firing and training times, sticking to public access routes, observing safety information including flags, fences, signs and by-laws; and reporting any ordnance they came across but not touching it.
People accessing military training areas when it was not safe to do so "not only places visitors in harm's way, but can also put service personnel at risk", the MoD said.
Brigadier Jonathan Bartholomew, of the DIO, said: "These beauty spots are shared land, where families, tourists and locals spend time. But it's also where our armed forces practise live-fire training, so it can go from tranquil to treacherous by the hour, 24 hours a day.
"It's key that we work together to share these spaces with respect and consideration."
