I am going to say something controversial: when I hear about adults who have gone through trauma and are suffering from PTSD I think I had experienced their total trauma events by about age 4.
Not controversial IMHO... but a little misguided. You're associating cPTSD with childhood trauma, when that is far from the fact. cPTSD is an outcome to when a person lives through complex traumatic situations. Childhood abuse by itself is not necessarily complex, and in fact, a very slim minority of abused children who get PTSD, actually fit cPTSD.
Interestingly... you compared yourself to soldiers. The facts are stacking up quite quickly that soldiers of multiple operations fit cPTSD more than PTSD due to the exposure and complexity of the trauma they're experiencing, and worse yet to your own believed controversy, they're becoming more standard fitting cPTSD than those with childhood trauma.
The problem with all this right now, is that there isn't a cPTSD diagnosis, and the original conceptions of this diagnosis were based by a childhood sufferer arguing for inclusion within diagnostic manuals, though those manuals have limitations on crossing between personality disorders which are related to adolescence and below. That very aspect is also in much dispute presently, as research is discovering that personality can, and does, actually change in adulthood when exposed to complex traumatic situations.
An example of this, is that cPTSD always included POW's, yet to be a POW you are typically an adult. By definition presently, you can't be diagnosed with personality reformation as an adult because it was always stated it happened prior to adolescence. The DSM has dropped its Axis system as a result of much new research on personality formation, more so, personality change after adolescence. Stay tuned to see what develops with the DSM over the coming decades.
So what you're saying isn't controversial, and actually not very accurate either in the scope of research and conclusions being formed in the last 5+ years about personality and complex traumatic effect. You're going to be quite shocked I think once a cPTSD diagnosis and subsequent data continues to form, as you will see a lot of adults who endure combat, those taken hostage for prolonged periods as an adult, those who get snatched up at 17 or so and sent into the sex trade industry for years before they may escape, and so forth, all fall into cPTSD.
Childhood trauma will be a minority of cases for it. It's like people perceive combat trauma is a majority for PTSD, when that is far from factual. It is a minority for PTSD diagnosis, civilian trauma is the majority.
