Soap sometimes has a bit of a tendency to ramble. When he does, he talks quickly which thickens his already prominent accent. It all turns into unintelligible 'Scottish babbling', as Ghost likes to say.

You, a new recruit for 141, happen to be Scottish. Soap has been talking to you and observing your training, obviously taking a like to you due to your similarities with him.

That's when he starts rambling, not at all expecting you to comprehend any of it.
