- AP means Army Point. It represents the overall power of your warband. Matchmaking is mostly using this value to adjust balance. The number of units in itself is not relevant, but can apply for specific unit types (like you can have only one legendary unit on the battlefield).
- Your units can receive permanent injuries (including death) from failed missions, bad events, or if getting KO in a match (it will then roll a dice and receive an injury, a "permanent" death, or no injury at all). You can buy fate cards to protect them, but except for loved units you should not worry too much and either go on with them or buy fresh new units.
- You can consider Stances as joker skills for your match. Each one has its own rules, wich should be explained on the associated tooltips.
Have a nice trip on the battlefield !
