Royal Marine recruits who hope to wear the famous green beret have been put through their paces for Exercise Final Thrust.
The recruits were asked to attack Scraesdon Fort in Cornwall, a 19th-century garrison formerly built to protect Devonport Naval Base and now used as a key training location for the Royal Marines.
“This is a culmination of their training,” said Captain Matthew Bentley, Troop Commander of 261 Troop.
“This is their final exercise and this is their final attack, so they’ve been out for about eight days conducting numerous attacks on various areas using helicopters.
"We’ve been in Bodmin, up at Davidstow Airfield then we’ve been yomping across Dartmoor.”
Room by room, the recruits clear the enemy they have been fighting and observing for much of the week.
“We’re what we call 'in the field',” explained Jared Selhi, "And that’s what the job is, it’s being in the field.
"It’s getting amongst it, getting stuck in. Last night we were jumping off of inflatable boats and doing cliff assaults and stuff.
"All the lads absolutely loved it, it’s what we joined for.”
Split into sections, the attack lasts for just short of 30 minutes.
The training programme is not known for being easy and, while 261 Troop started as 52 men, it is now down to 31.
“Obviously it’s been very difficult at times,” recruit Aidan Lyne told Forces News.
“But when you’re three, four, five, six months in and it’s relentless day after day, you’ve got to dig deep to find that something inside of you that keeps you going each day."
However, it is not over yet for the Royal Marines recruits.
They have another two weeks of intense training to go and that includes a Commander test and the infamous 30-miler across Dartmoor.
