British Royal Marines of 40 Commando Bravo Company, 47 Commando and 29 Commando detachments and US Marine Corps (USMC) have conducted jungle exercises.
The intensive experimental exercise took place on the Pacific Island of Guam, where temperatures were recorded to be above 40°C and 79% humidity.
Participants were provided with an opportunity to hone their jungle skills and test new tactics.
The exercise involved commandos taking part in jungle ambushes, reconnaissance patrols, break contact drills and amphibious beach raids.
These activities were carried out together with Cherokee Company, Battalion Landing Team 1/5 of the 31st Marine Expeditionary Unit.
40 Commando marine McDonnell said: “This was all carried out using techniques from both sides of the pond and we learned valuable lessons throughout.
“It was mainly an experimental exercise involving jungle patrolling, contact drills, land-to-sea defensive techniques and working at reach with limited support.”
In addition, marines also practised and trialled USMC’s Expeditionary Advanced Based Operations tactics, which are used to gather intelligence and track and confine enemy forces’ movements.
This is usually carried out by deploying small teams with restricted support to islands or chokepoints in strategic critical areas.
Marine Ridgeway said: “We spent a few days in the jungles and hills of Guam practising USMC Expeditionary Advanced Base Operations tactics for locating and targeting enemy ships from ashore.
“We also carried out break contact, casualty evacuation drills alongside patrolling in small teams.”
Furthermore, participants from 47 Commando shared skills and experience related to close-quarters battle and day and night ship boarding and capturing using a replicate.
