How do you find out which troop type defends a tile in Dragonfire?

To pick the right army you want to know the defender's troop type (Cavalry, Archers, Spearmen, Shields) so you can play the counter. But:

• The enemy type is only shown on tiles below level 10.
• From level 10 upwards the matchup reads "Unknown" until you've scouted the target.

So:

• Below level 10: you can see the type → send the one that beats it (+7%) with green dragons on it.
• Level 10 and above: scout first if you can, otherwise bring a flexible army or several waves, because you could walk into a bad matchup blind.

Don't waste a big single-type army on an unscouted level 10+ target: the −7% of a bad matchup hurts.
