Thank you to both Jonpas and Chairborne 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.
To show that the UH/MH-60 can use both the FRIES system and the hoist on the right side of the troop compartment; as the hoist is higher on the airframe and in front of where the FRIES comes out of the crew compartment. So it is feasible for both systems to be in place on the Blackhawk/Seahawk at the same time.
Better view of locations of hoist and FRIES bar location.
FRIES in use with hoist shown to right and above the FRIES bar.
MH-60 DAP Variant should NOT have FRIES options.
HH-60 coming in on fast rope exercise with FRIES extended.

Better view of SH-60 with FRIES and hoist on right side of helo.
Maybe the best view of the FRIES bar extended on the right side of an SH-60 doing fast rope exercise.
All UH-60 helos can have the external hoist removed as referenced below.
No external hoist seen on US Army UH-60.
Other nations UH-60 without hoist attached as well.

This is NOT A DAP unlike the name of the photo states.
