They had planned the mission for a month before it was carried out.
During that time, they had made almost perfect preparations.
The preparations they had made, no one could find fault with them in any way.
It could be said that they had made no mistakes!
But when they actually acted...
It was a fiasco.
It was the only mission he hadn't completed since joining the SEALs.
When performing that mission, the opponent seemed to have insight into all their plans in advance and dug a hole for them to jump into one by one.
As a result, all his brothers were killed, and he, too, barely escaped with his life.
He knew that there was a mole on his side.
The mole told the target of their plan, thus led to their defeat.
And the mole was not one of his brothers.
It was a high-ranking official who was involved.
He told the leader about the mission plan.
