It takes five or six people to operate a howitzer – a weapon used by many militaries around the world, including the US, New Zealand, and now Ukraine.
A sergeant from 29 Commando Regiment has explained step by step for Forces News how the British military's L118 105mm light gun operates during a live firing exercise in Oman.
The light gun is designed and made by Howitzer and can fire high-explosive rounds up to 17.5km away.

The high-explosive rounds weigh 16kgs, and the gun can fire a range of other ammunition including illumination rounds, which can turn night into day for advancing troops.
Smoke screening rounds can also be used to conceal manoeuvring units and used as part of a deception plan.
