Protector Defender (Chinese: 铁卫; Pinyin: Tiěwèi; lit. "Ironguard [Defender]"), colloquially known as Normal or Tank Defender, is a branch of the Defender class in Arknights.

As their name suggests, Protector Defenders focus on withstanding attacks and holding off enemies' advance due to their block count of three. However, most Protector Defenders have low ATK and an attack range of the same tile as themselves, although some have moderate ATK and an attack range of the tile ahead of them like other melee Operators. Regardless, Protector Defenders have no base RES.

Modules

• The PRO-X Module allows the Protector Defender to withstand attacks from strong melee enemies, especially when combined with DEF buffs to bolster their DEF further.
• The PRO-Y Module improves the Protector Defender's blocking capability and notably allows them to block certain enemies such as Theater Golems (which are counted as 4 enemies when blocked) on their own.
