Clash-of-clans – In clan wars, on the war map, what do the troops standing outside the base represent

Official answer from Supercell. Scroll down to about mid page. War map rank is determined by overall defense.

• Once a match is found, players are sorted on the map from strongest to weakest, in terms of defence power of their base, i.e., defense levels, hero levels, traps, etc.

• We do not take TH levels into account. Instead, we only use overall strength of all defence elements in player’s village. For example, a TH8 with higher level defenses than a TH9 will be ranked higher than the TH9 in the war map.

The troops in the clan castle indeed defend each attack.

You can be attacked more than two times in a war, but your clan castle is always full for defending against those attacks, full of whatever was in the castle at the end of the war's preparation phase.

Additionally in war:

1. Heroes are always active to defend your War village.
2. Defenses like Xbows and Inferno towers, and traps are preloaded
3. Any defenses under construction are active in war, unlike your home village. In fact, any defense STARTED prior to the end of preparation day is active and defends your war village.
