“Tonight we’re doing a set of steering and breakdown drills,” explains Lieutenant Stephanie Buttery.
“Which are to increase redundancy if we were to lose steering in a war scenario or even just driving around.
"At the moment we’re off the coast of Oman and so there’s a lot of fishing nets and other sources of interference for our rudders.”
Amphibious landings require a lot of equipment - to ensure that an effective troop of marines can be deployed ashore at the time and place of their choosing - and there is one bit of kit that’s vital to any assault:
“The landing craft utility is the heavy lift of the Royal Marines,” said Major James Smith of 30 Commando.
“This will get up to a hundred packs of a company’s strength of marines from ship to shore.
"It can also take up to three Viking armoured vehicles or, if we need to, one Challenger 2 main battle tank."
