From this tournament https://www.youtube.com/live/rJF8kXpJzLg

This room has 2 guards that patrol a "room" that is basically a hallway, which leads to a door that needs to be opened with a wheel (like the doors in the Tanker). Once you open the door, it's down the ladder with Emma. There's no node (not nerd, NODE) so there's no radar. It's one of the last, if not the last, true stealth sections in MGS2, not counting that one hallway in Arsenal Gear.

The guards alternate facing the door you need to open, and the entrance to the hallway, but it seems like at all times there is one guard staring at the door, and one guard staring at the hallway.
I'm playing on Normal difficulty, and I'm trying to not use my tranq gun, because I feel it makes the game way too easy. But I haven't found a way to get through this room without raising an alert or just knocking out the guards. Am I missing something?

Lots of examples of JP covers being obviously better (ICO is too funny) but I'm split on MGS2.
