If I may, kindly - for the sake of everyone not schooled in jargon - at least say what you're referring to once directly before launching into acronyms. Not necessarily for the person equipped to directly answer your query, but for the other peoples' reading ease.

For the record:

SNLF - Strategic Naval Landing Forces - the Imperial Japanese Marines.

IJN - Imperial Japanese Navy

IJA - Imperial Japanese Army

TO&E (AKA TOE) - Table of Organization and Equipment
