A few things that are unclear to me about sacking generals
1) when you sack a general, is he removed immediately, or is his sacking attempt resolved at the next interphase?
2) how do you see the pool of generals that might be available for replacements if you choose to sack someone? I would think it would be important to know if you what the abilities of replacement leaders are before you make the decision to show a leader the door.
3) once sacked, how do you place a new general in command of the army?
