So I hear a lot of the "Lecarno did it because it would show what a brave, bold, out of the box thinker who shows initiative and doesn't follow the rules and is a man of action who gets results damnit.
OK so in theory this makes sense, some of the most famous characters from Dirty Harry to Batman are guys of action who don't follow the rules and get results.
Star Trek has echoed this trope with Kirk, NuKirk, Picard, Riker, etc. having the positions they do because they possess those traits and have shown them in action.
The difference is that when these characters demonstrated these characteristics they were in some kind of serious, often life or death, situation where playing it safe and going by the book would have probably ended in disaster and they had enough of these traits to do what would save them, even if it meant breaking some rules and taking risks.
Lecarno uses his willingness to take risks and break rules not to save lives or prevent a disaster, but to preform some little stunt that was expressly forbidden. It wasn't like if he didn't have his squad do the starburst stunt that people were going to be killed or worlds wiped out, all that would have happened is the audience wouldn't have seen some kind of cool flying trick. Hardly a situation that calls for those traits to be shown. It doesn't even show that he could think quickly and rapidly adapt to unexpected situations, he had obviously been planning and practicing to do this for months, it wasn't like they were doing their demonstration and had a spur of the moment thought and he said "OK squad......starburst on 3".
The characters that were rewarded for these traits were confronted with unexpected and dangerous situations that called for quick thinking and action which justified doing things differently and breaking a rule or two.....Lecarno was just trying to look cool, which does not justify those kind of actions. Totally different scenarios.
It's like the stupid crap Top Gun fed us.....That if you're "The best" it makes it ok to constantly do dangerous and/or forbidden things. Of course this was the same film that wanted us to believe that the Navy's soultion when a pilot is deeply emotionally disturbed is to get him up and flying as soon as possible and actually ship him out to a combat situation and put him right in the middle of the action........Right

The military is just DYING to find soldiers or pilots who are having psychological issues and throw them into combat ASAP because their problems will actually make them better fighters and the combat itself will probably cure them of their problems.
