Using a BFPO address

A question about : Using a BFPO address

My son has just joined his regiment in BFG and has needs me to send over his paper counterpart of his driving license. He's sent me his address, but looking online I'm not sure how to write it on the envelope.
He's given me his regiment, barracks and troop details and basically the postal address of the barracks as well as the BFPO no.
Do I use all of this, or just his regt, barracks and troop details with the BFPO? (I saw an example like this online)
I'd like to get this posted as soon as possible, so before he's clocked off for the day IYKWIM or I'd ask him myself.

Thanks in advance.

ETA: Would it get there quicker if I just use the postal address? I've read it can take up to 4 or 5 weeks using BFPO system.
