Like a lot of the crossover between civil/military equivalents, it's a tough one to call. In my experience, LAMEs routinely get our hands as dirty as any military mechanic, but also use their breadth of knowledge and experience to make judgement calls on, say, deferral of defects equivalent to that of a military engineering officer.
As an RAF Corporal, I was able to Co-ordinate a F700 and release for flight. What I couldn't do was close open jobcards. So as long as nothing is reported by crew & nothing is found during flight preparation I could release the aircraft. As soon as maintenance is required (other than that needed for flight preparation) I would have to get the jobs signed off as complete by a SNCO or above. But that is no different than for the aircrew, who were also able to do this and they have a degree in sociology not engineering!
