War Attacks

1. Don't overestimate your ability, go a bit lower if necessary but not so low that lower team members can not attack anything.
2. Your aim is to get three stars, don't attack base with existing star(s) unless there is no alternative.
3. Use your best troops and both attacks if you can.
4. If there has been an unsuccessful attack, study the replay to learn of possible weaknesses.
5. Until you have TH7 or better and are able to do a dragon attack or equivalent you MUST draw out the cc troops first and eliminate them (with archers probably). 
6. Study the base carefully to decide on a strategy and where to drop your troops and in what sequence. 
7. It is better to go with an all air attack or all ground attack to avoid half the defences.
8. If you are unable to participate in a war e.g. on holiday, you can exclude yourself by the CLAN WARS option in your profile settings.

Looting
Do not attack a base which you know you cannot 3 star just to maximise your loot unless given permission.
This is a kickable action.
