Minecraft wiki entry for Armor_Stand, associated text: In Bedrock Edition, armor stands can be affected by status effects. They can be 'killed' by Harming and Decay splash/lingering potions, lava, fire, and campfires, and they play the player death sound and fall to their side and disappear, yielding no armor stand item. If an armor stand is equipped with an item or armor, that item or armor is considered as "naturally-spawned equipment" with an 8.5% chance of dropping when the armor stand "dies" from the Instant Damage or the Wither status effect. If the dropped item is any form of weapon, tool or armor, it drops in a badly damaged state because the game considers it as "naturally-spawned equipment".[1]
