I just want to point out that holding out the shield far in front of the body like in page 13 has no benefit and can actually cause yourself to be disarmed and disoriented from your opponent hitting one side of your shield and cause it to flip and leaving you vulnerable. Even if you have hands of steel, it would've definitely hurt your wrist or injure your palms. All I need to defeat this stance is to hit either the right or left side of her shield and she'd have been left wide open for the second attack.
Though it's quite funny how in some panels she has the arm strap and in some panels she didn't have it. I just assume the artist didn't know how shields work.
This stance is only useful if you're in a formation as a second line soldier with a shield and a long spear, locking shields with the soldiers in the front-most line, such as in a phalanx or a legionnaire's auxiliaire column. It's easily defeated in a duel.
Anyway, thanks to the translator team for sharing the chapter.
