Yeah, some people seems to think a knight was carrying around hundreds of pounds of gear and armor, and if he fell he needed a bunch of guys to help him get back up. 
Last time I was in a combat area I was carrying hundreds of pounds of gear and armour and needed a bunch of guys to help me up if I fell.
In actual fact probably around 100lbs of kit, rifle, helmet, body armour and boots. Spare link for the LMG, spare mortar rounds,occasionally link for the GPMG, radio, spare batteries, NVG's, grenades, smoke, water, scran. In actual fact, it was worked out that soldiers carry pretty much the same weight now as the Roman army did, verything has been made lighter and more compact but you end up carrying more crap as a result.
