This guide is to explain how sudden strike works and what those % means
 
 

Intro

Many people don’t understand why there is a “chance” for sudden strike and how the odds are calculated. This guide will give you all you need to know about it.
 
 
 

The Yellow Bar

 
When you are in visual range of a garrison, you can see its shiny yellow bar flashing over its head, and is ticking its way down.
 
 
This bar indicates how long before they know what’s going on and becomes combat ready.
 
 
The bar length is randomized between 15~45 minutes and you have no way to know prior to it starts ticking, hence the “chance” of your successful sudden strike.
 
 
 

Alarm

When you are discovered by a combat ready enemy, they will send out an alarm and it’ll show a timer on your clock indicating “Sudden Strike Impossible”. It’s more complicated than that.
 
 
When the alarm is raised, all active garrison starts ticking down their own yellow bars. If you already have a force close enough to the enemy, you may be able to reach it before the yellow bar runs out, thus still achieving sudden strike.
 
 
After the alarm is over, there will be approximately 2 hours of time for their yellow bar to reset. During this time, if you attack, they will still be considered on alert and they will be airborne while being able to report your location immediately.
 
 
 

Prize Ships

They have a approximately 7.5 minutes fixed timer andare considered on alert when departing a city, which over a certain amount of time may reset and become ambush-able.
 
You can use Fire Control Radar to see if they have yellow bar over their head. If not, it means they’re on alert at that moment and may instantly report you and raise alarm.
 
 
(Not verified if normal mode spawn these)
 
On hard mode only, prize ship may have escort ships that are equipped with a 500km range radar, making it nigh impossible to strike before they raise alarm. Make sure you brought ELINT scout to prevent raising alarm by accident.
 
 
 

Conclusion

If you want a totally stealth playthrough, Fire Control Radar and ELINT is mandatory to not accidentally run into an on-alert trade convoy. Otherwise, make sure you can bridge the visual distance (75km at midnight, 100km at noon) within 15 minutes to guarantee sudden strike on garrisons.
