haha! you horrible sods! poor boy is asking a serious question, and you lot are terrorising him!
well mate. there all fairly basic... they will ask you all manner of questions on weapons, and transport, and equipment, so start learning... questions such as.. what is load capacity of a landing craft ect... what is a javalin? what is bowman? calibre of the SA80 rifle?and so on.....
they will also explore your own personal reasons as to why you want to join the marines.. so really give it a good think over....
most likely they will ask you about your thoughts on killing another, and potentially being killed yourself....
they may ask you to give an example of when you were in a position of responsiblilty or an organisational role, also whether you captained any sports teams and so on... hobbies ect...
overall, just make sure your equipment, weaponry and transport knowledge is up. oooh, and while i think about it... knowledge of the corps.... history, current operations, the different branches of the corps, ie 40,42,45, 29 battery, 59 assault, and 20 commando engineers.. i think these are the right ones, but my interview was a few months back and i cant remember everything!
and finally... per mare per tarram.. by land and sea. the marines moto!
good luck fella, and get revising!
