- reload before suppression fire less often in dangerous situation, also check AP_MINIMUM so we don't reload when really low on APs
- use CanNPCAttack() check only for sniper and suppression fire as only these actions need usable gun
- when trying to step back to deploy mortar, check if we can reach the spot and have enough APs
