The First Sea Lord has been asked for a plan to “take forward” the work of the Royal Marines, as ministers effectively confirm they’re again reconsidering the future of the corps’ two amphibious assault ships.

Professor Michael Clarke explains what’s going on, and former Royal Marines Commandant General, Major General Buster Howes, tells Sitrep the Defence Secretary needs to think “very very carefully”.

The Defence Secretary tells the world “watch this space” for possible reprisal strikes against Houthis firing missiles at the Red Sea. British Sailors are already on constant watch there, and former Royal Navy commander Tom Sharpe explains what they experience when missiles and drones are incoming.

And how do you learn to command a multi-million pound military craft in an environment less explored than space? Ryan Ramsay who used to lead the Royal Navy’s submarine command course shares stories of near misses, pushing people beyond their limits, and how he’s turned it all into life lessons for a new book.
