HMG21

HMG21 and HK21 are two characters in the mobile game "Girls' Frontline" (also known as "Dolls' Frontline" in Japan), and though their names are similar, they are actually different Tactical Dolls (T-Dolls). HMG21 is a heavy machine gun T-Doll who excels at providing fire and defense buffs to shotguns (SG) in front of her, making her a great support unit. However, her skill activation slows her movement speed, which makes her slightly less effective in battles requiring precise control, like boss fights. HMG21 can be obtained through T-Doll production and has multiple skins to choose from. HK21 is a light machine gun T-Doll whose backstory is related to the G3 rifle, and she's considered a "sis-con" due to her attachment to her sister G3. HK21's personality leans towards rebellious, and she even dyed her hair blonde to get her sister's attention. In the game, HK21 can be obtained by drops in event levels or completing specific campaign levels. She is equipped with a 7.62mm caliber machine gun, has multiple combat styles, and has a rich story background, making her an indispensable character in the game. In conclusion, both HMG21 and HK21 are important characters in "Girls' Frontline", and they each have unique positioning, skills, and backstories, adding to the game's strategic depth and fun.
