For example (note "combat engineers" is in quotes):
"Military experience?
All branches of the military have engineers doing genuine engineering work. In this regard, the military is just like any other employer, and the engineering work experience counts. However, work performed by "combat engineers", electronic repair technicians, and so on is generally not true engineering work." [1]

The liberal use of the term 'engineer' to describe technicians or mechanics does irk many in the engineering fields, however.
In Germany, the term is protected, so it is illegal to use the label without holding full qualifications, like 'doctor' or 'lawyer'.
Let's acknowledge that language grows and changes as new concepts are invented.
