Emergency Raiding with Defensive Units

Arr pirates!! Have ye ever seen a very sweet target but all yer army is out raiding and pillaging somewhere and ye just don't have the troops to raid this juicy nice Haven that ye found? Well, there are 2 choices ye can make from this:

1) Ye can sit and wait for yer offensive troops to come back to yer Haven so that ye can send them out to this new target.
But remember the longer you wait the more chance some other pirate will raid and take all those resources.

2) Take a risk and send yer DEFENSIVE pirates to quickly grab those resources!
But here also, remember that this be super risky undertaking and ye should do this when y'ar relatively sure that there be no defense out there.
How can ye be sure?
Well, if it is a target ye raided many times before and there is a good history - is one indicator. If the target be close to yer Haven so that ye get in and out quick with yer army is another indication.
But nobody can give ye a 100% guarantee - this is a risky action which best be taken with a barrel of Rum emptied all by yer-self.

Check below picture for an example me scouted a sweet target with ~19k resources and sent a whole heap of defensive units and grabbed a very nice chunk of gold and lumber and Rum. All my Haven celebrated into the morning, at least half of that Rum was drunk :)
