The 92F Mos is a petroleum supply specialist
11B is for Infantry. 30 is for skill level of Staff Sergeant (E-6). G is an Additional Skill Identifier (ASI) meaning Ranger qualified. You probably would not want to mess with a soldier with MOS 11B30G.
45 is the soldier's Career Management Field (CMF). Combined with the following letter, you have the Military Occupational Specialty (MOS) - the soldier's career field. 45k used to be the MOS for Armament Repairer - when the Army reclassifed its MOS structure from 2001 - 2004, this MOS became 91K. So, to hold this MOS, they had to be in prior to 2004 or so. The '2' indicates a skill level - skill level 2 indicates they held the rank of Sergeant. The 'O' (not a zero) indicates they have no Special Qualification Identifiers or Additional Skill Identifiers. These identify various skill sets which a soldier possesses... for example, if they were Airborne qualified, they would have a 'P' rather than an 'O'.
There are multiple regulations which blanket every MOS. There are multiple regulations pertaining both to all skill levels and to Skill Level 4 personnel. You're not going to find the entire scope of regulations in one paragraph.
A hard skill is a skill that is tangible and measurable. Hard skills can easily be taught and tested, such as shooting a basketball, reading, and cooking.

I'll break it down for you 11B - infantryman, enlisted. This part is the actual MOS. 1 - lower enlisted, ranks Private through Specialist. This is the skill level identifier. P - Airbourne qualification. This is an additional skill identifier. 2C - qualified to operate the Javelin anti-armour weapons system. This is another additional skill identifier.
Every difficult skill is hard to master.
