That was precisely my point.
They wrote the ROE to tie your hands, but had an escape clause for themselves, when it came to the consequences of not acting.
5 seconds before the suicide boat hits you, its a violation of ROE to destroy it. But 5 seconds after it hits you, you are at fault for not engaging what turned out to be a threat (oh, and you are dead).
Which is exactly why, as a Fleet TAO, I never gave a crap about the ‘official ROE’. My personal ROE took precedence - ‘Nobody on my ship will ever die because I did nothing’. I had all the keys, weapons release authority and zero qualms about sitting at the long green table.
