Im slightly confused about this, hope its not a silly question but I've googled and searched this forum to no avail. Army Officers are trained at RMAS, Naval Officers at Britannia Royal Naval College at Dartmouth. What about the Royal Marines? I have found mention of Marine Officers having completed 'Royal Marines Young Officer training' but what and where is this? I cannot find any substantial info on the RM or Navy websites, I hope somebody here is in the know! Also, is it possible to go through RMAS, join your Army Regiment, then transfer to the RM? (Or even commission directly into the Marines on graduation?) Presumably if this is possible, you have to complete the Commando course etc. Would be much obliged if anyone can clear this up for me!
