Fighting the Ocelot Unit on VE/EZ by iLL_pazzo
If the Ocelot unit is worth skipping on Very Easy depends on your execution during the Ocelot Unit fight.
Plus without the mk.22 and m1911 in your inventory you'd do the menu after the waterfall to reequip everything also a tiny bit faster.
Depending on the timing method, you'd want to run the entire game in 30fps as to not lose time to swap between 30fps and 60fps – should
timing be based on RTA (including Load Removed Realtime or LRT). If the timing method is IGT, then the fps setting change does not count
as the pause menu also pauses the IGT ticking forward.
In general it is faster to airwalk based on this comparison:

Notes:
EXTRA: Make a visual cue to consistently headshot the sniper, if you miss he'll spot you (unless you are below the crates in the corner, but at that point you'll most likely miss the cycle for the assault squad)
Stunless Route - pre-fight broken window by Setharooni
Airwalk skip by MetalGlennSolid
MK.22 the bottom guards first before distracting the rooftop sniper with an indoor ceiling shot.
Roll out the window, run behind the northern end wall to throw a stun on top of the roof to take out the sniper.
Finally take the ladder up and leave with Airwalk Skip.
Airwalk skip by Metsa
Utilizes a stun out the window first, then tranq the 2 bottom guards and the rooftop sniper to access the ladder quickly.
Rooftop movement only feasible with keyboard inputs, stick movement on gamepad may lead to missing the gate if not careful.
Airwalk skip with 13 swaps by Tromboncino
Most optimized variant yet.
The amount of times one needs to swap may be dependent on PC performance and not exact.
Testing strats yourself can help you understand your own minimum amount of swaps.
