Attack Only and Transfer Only

Attack Only and Transfer Only are advanced options for customizing how your attacks happen.

"Attack or Transfer" is the default option that you will use most of the time. This causes the armies to attack the destination if it is an enemy or to transfer to the destination if it is friendly.

Sometimes the ownership of the territories can change before the order takes place. For example, you may think you are issuing an order against your own territory, but an enemy may capture it on the previous order.

Specifying "Attack Only" will cause the armies to attack if the destination is an enemy, or do nothing if the destination is friendly (i.e. one of your own).

Conversely, specifying "Transfer Only" will cause the armies to transfer to the destination only if it is friendly and will do nothing if the destination is an enemy.

Example

Assume you are blue, and you suspect green will be attacking you on the next turn. Since your 69 on Ufa (A) will be crushed by their 113 on Eastern Kazakhstan (B), you want to bring 71 in from Georgia (C) into Ufa to help defend your bonus. So of course, you issue a transfer order of 70 armies from Georgia to Ufa.

However, even if you issue the transfer order as your first move, green's first move may happen before your first move. If green attacks Ufa on their first move, they would capture Ufa before your armies in Georgia transfer in to defend it.

In this case, you can issue your move as Transfer only. While this won't help you safe Ufa, it will make it so that if Ufa falls, the armies on Georgia don't suicide themselves into a big stack. Instead, they would simply stay on Georgia.
