>>> Javelins don't cause this kind of damage. People with military experience would know that.
>> Not necessarily. I'm sure there are plenty of people with military experience who wouldn't know that (e.g. don't have experience with Javelin missiles for one of numerous valid reasons). It's like someone can have lots of programming experience, but not know some specific about how Java works because they haven't worked with Java.
> Maybe it's like someone can have lots of programming experience, but not know what for loop is. I'm not sure.
No, I'd say it's more like an embedded C programmer not being able to recognize symptom of the Java garbage collector going awry. Being able diagnose from a photograph what kind of weapon was used to destroy a tank seems like an extremely specialized kind of military experience.
