No. First, nothing in this game is courageous as it is just a cartoon, not real. However, if you are talking cartoon courageousness then still no. There is no flashing, no darbar, no indication whatsoever of the attack until after it's successful. So zero probability of the mission being a failure. Zero probability of going against any resistance. 100% probability of success. And it's all based on a "feature" of the game, namely that the HQ can't be bothered to pick up the phone when the first shell lands and tell someone it's under attack.
wait a minute here.....
These guys do the same thing to strat factories. One example took place 3 days ago. They drove a total of 8 hours to a radar, barracks, and ords factories leveling it to 0%. I had a goon on standby the entire time and after each strat air dropped supplies. After the ords factory they drove a short 30 miles to the HQ and dropped it twice.... then camped the spawn for m3's and got around a dozen kills before landing them.
There is never a 100% guarantee of success. There have been times where people gets disco for whatever reason then come back with a dot only to have a spy kill them half way there.
Not flashing the HQ is brilliant. It takes a lot of time to zero in a target from 3-5 miles away. Sometimes there is no direct line of sight. Sometimes after its dropped they destroy the resup convoys afterwards with no line of sight.
