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.

TH5 balloon attack video

TH6 balloon attack video

Request

lvl6 balloons

Operation: 

1. Lure ALL the clan troops, if they have 11 archers and 1 or 2 wiz you may have to drop several troops within range before they all pop out, if the cc is right in the centre you can drop a balloon to pull the cc troops.
2. Kill the clan troops with your archers.
3. Drop balloons (not the clan balloons, your balloons) towards all defences that need to die to clear a path towards the opponents AD. Drop 7 or so of them in streams towards any defence that stands in the way of the clan balloons having a path towards the AD. Then as those balloons are in the air, just drop the clan balloons straight towards the AD.
4. Drop the remaining balloons directly towards the  wizard or archer towers.
Try hard to avoid getting all the balloons in one bunch, you want 2 groups of balloons at least for the clean up phase.
5. Drop heals as needed, probably while the AD is still active and you can cover the streams and the L6 balloons at once. You want to keep the L6 balloons alive, drop the heal on and ahead of the balloons, covering as many defences as possible so the balloons can be healed for as long as possible.
6. Once defences are down drop remaining archers/wizards to clear up, not forgetting outlying buildings if any.

AD = Air Defence

Dragon notes (ongoing)

1. Your aim is to take out the AD's as soon as possible.

1. Channelling (this is the key) To get the bulk of your dragons towards the AD you need to remove the side buildings first, if left untouched the dragons will wander off course and leave themselves vulnerable to the AD. You can do this by dropping one or two dragons each side of the intended path and waiting until they have destroyed some buildings, then drop the bulk of your dragons and your CC dragon/balloons towards the AD(s).

1. Don't drop all dragons in one place, it makes them vulnerable to splash attacks
2. Spells
1. You can remove the deepest AD with 3 lightning spells.
2. Drop rages on and ahead of the advancing dragons to get them to the centre faster.
3. If one of the AD's is near the edge you might be able to remove it with your king.
