Best weapon against Lorica Segmentata?

[Nurglitch]

I've seen this comment. I consider it unlikely, but even if, the renaissance and heavy baroque armour was heavier and covered greater area of the body than segmentata. Renaissance cuirass designed to stop a musket ball could reach 5-7mm of sloping thickness. And a halberd was primarily meant to allow the infantry to mess up heavy cavalry. You hit the target and something dies. The rider, the horse. If you get it tangled (that's what the hook is for), just pull and the rider comes off the horse.

was better armoured than a legionary. Really.
