EXAM 1 (D) Flashcards
What does GMRS stand for?
Ground Marking Release System
What i s the purpose of GMRS operations?
Procedure is used to covertly infiltrate a small unit into a denied area without use of radio communications.
Requires a trained reception party on the Drop Zone (DZ) to mark the Release Point (RP) with a specified ground marking.
GMRS requirements
Must have visual conditions
Air Force Combat Control Teams (CCT) or Air Force Special Tactics Team (STT) are not required on the DZ
No special aircrew or A/C requirements
GMRS jumpmaster proceedures
The Jumpmaster must spot the ground marking out of the left side of A/C
If the A/C is not properly lined up, the Jumpmaster will not exit the jumpers, even if the “green light” is on
Who creates the RP during GMRS operations?
The DZSO/DZSTL is responsible for computing the Release Point (RP) and placing the markers IAW the RP computations.
What three factors are taken into account to compute the RP?
DISPERSION
WIND DRIFT
FORWARD THROW
What is dispersion?
The the length of the pattern formed by the impact of the jumpers
What is Wind Drift?
Wind drift is the effect that the MEW and drop altitude will have on a parachute with no Jumper input.
What is Forward Throw?
the horizontal distance the jumper or bundle will move from exit to parachute opening in the direction of flight
What is the forward throw from helicopters?
Speed in knots divided in half
What is the forward throw for fixed wing aircraft?
Personnel/Door Bundles C-130 (229 meters)
HE C-130 (458 meters)
CDS C-130 (503 meters)
What is the forward throw for fixed wing aircraft?
Personnel/Door Bundles C-130 (229 meters)
HE C-130 (458 meters)
CDS C-130 (503 meters)
What is the forward throw for fixed wing aircraft?

What are the three kinds of marking formations for GMRS
Inverted L
T
H
What is needed if the ground marking for GMRS is masked (15:1 clearance ratio)
Personnel = A code letter H E A or T is placed on the departure end of DZ
CDS = VS17 placed at far end
