Thank you both for your help on Discord. I have updated the ticket to show FRIES systems in place on UH/MH-60 Blackhawks with external hoist hooks for SAR/Medevac missions as well.
Several variants of US UH-60 helos are missing the ability to equip the FRIES system for fast roping with the ACE FRIES system. The FRIES system is known to be used on all UH-60 variants with the exception of the DAP variant which does not carry troops at all.
Listed specifically under the Special Operations point at the bottom of the page: https://lockheedmartin.com/en-us/products/sikorsky-black-hawk-helicopter.html
Shown in detail in the video linked here: https://www.youtube.com/watch?v=o-F2vhXfyME
To show that the UH/MH-60 can use both the FRIES system and the hoist on the right side of the troop compartment. So it is feasible for both systems to be in place on the Blackhawk/Seahawk at the same time.

USAF HH-60 with hoist for SAR and FRIES for fast rope; the FRIES bars are internal to the compartment and extend as needed. You can see it directly above the heads of the guys in the back.
Image for the FRIES system in a UH-60. This time showing the extra internal fuel tanks also added with the FRIES bar system (look for red hook up points) which extend out to allow fast ropes to be dropped down on each side of the helo.
