TCCC
Expand the MARCH acronym
M - Massive bleeding
A - Airways
R - Respiration
C - Circulation
H - Hypothermia and other injuries
Filtration vs purification for water treatment?
Filter: Physically strains out protozoa and bacteria
Purification: Kills microbes directly
Cooper's Color Codes
White: Unaware, zoned out
Yellow: Relaxed but alert and ready.
Orange: Identified a possible threat, ready to act.
Red: Action, high alert
Black: Panic, frozen, "internal"
What information does a declination diagram provide?
Angular relations between true north, grid north, and magnetic north.
Command and control versus Communications
Command and control: "The Brain", exercise of author and direction of a commander to accomplish a mission
Communications: "The nervous system", converting data into a signal, passing that signal to a distant point, and converting the signal back into data for decision making.
Communications enables command and control
Lt Parent charges the enemy with his KABAR in the pitch black but trips over branches in the Quantico Highlands and ends up with a KABAR in his thigh. Lt Parent applies his own tourniquet, and later experiences: rapid breathing, lack of focus, sweaty, clammy and pale skin. What is Lt Parent experiencing?
Shock
Four critical areas of detection on the human body?
Head, shoulders, waist and ankles.
Parts and roles of the autonomic nervous system?
Parasympathetic: recovery, rest and digest
Sympathetic: action, fight or flight
Parasympathetic backlash: The transition from SNS to PNS. Body neglects duties of parasympathetic, results in a less effective fighter.
Three types of contour lines?
Index - Thick lines with written elevations
Intermediate - Thinner lines between index lines
Supplementary - Broken lines to provide more information. Elevation is one half of a normal contour interval. Used in areas with minimal elevation differences.
Two modes of radio wave propagation
Ground waves: Travel from transmitting antenna long surface of earth. Obstacles including vegetation, weather, man-made features impact transmission.
Sky waves: waves travel up to edge of Earth's atmosphere and bounce back, allows long range transmission
Common tourniquet errors (3)
Windlass rod not tight enough
Self adhering velcro strap not pulled tight enough
Tourniquet not applied fast enough (<1 minute)

Expand SMITR
Strengthen: Enhance individual and unit resilience via training, cohesion and leadership.
Mitigate: Rest and work cycles, ensure Marines are fit to work.
Identify: Know when your Marines deviate from typical.

Less than 180 -> Divide by 3. Move bezel counter clockwise.
More than 180 -> Subtract from 360 and divide by 3. Move bezel clockwise.
The three major frequency bands and usage
HF: ~10 MHz. Long distance transmission.
VHF: ~100 MHz. Used for line of sight transmission, e.g. squad to squad or platoon level transmissions.
UHF: Up to ~500 MHz. For aircraft.
What should be done after moving a casualty with a tourniquet applied away from enemy fire?
Confirm tourniquet did not loosen.
Lt Hoyman spits out sunflower seeds as he is patrolling. Eventually, a clear trail of seed husks mark his exact trail. In technical terms, what did Lt Hoyman leave behind?
5 Stresses of Combat
Boredom
Fog of war
discomfort and fatigue
extreme risk and fear
casualties
The four colors on a map and their meaning
Black: Cultural/Manmade objects such as buildings.
Red-Brown: Cultural features, all relief features, non-surveyed spot elevations, and elevations such as contour lines.
Blue: Water features
Green: Vegetation
The four ways COMSEC is implemented
Crypto security: Prevents enemy from understanding the transmission.
Transmission security: Protect the transmission from interception entirely.
Emissions security: Reduction or elimination of emissions to deny the enemy information.
Physical security: Safeguard the classified equipment from access or observation (don't leave your radio behind.)
What DD form is used for reporting TCCC to higher medical?
DD FORM 1380
Considerations for field water sources?
-Contamination like dead animals and chemicals
-Stagnant or flowing
-Fresh or salt
-Run off
-Tactical location
The nine common elements of combat
Exogenous:
1 - Confusion
2 - Casualties
3 - Violent sights/sounds
4 - Continuous operations
5 - Communication breakdown
Endogenous
6 - Discomfort and physical fatigue
7 - Fear, stress and mental fatigue
8 - Homesickness
9 - Feeling of isolation
Lt Arritola, Hoyman, Hales and Parent decide to shoot an azimuth due north to intersect an unpaved road on a map. What should they also do before departing to make sure they end up where they want to?
(Hint: They did none of these)
Calculate the distance to the road and the pace-counts
Make a list of collecting features to ensure they are on track.
Decide on a catching feature or pace-count maximum to then turn around at.
These lieutenants ended up 800 meters north of SLR with 10 minutes to make it back before drop-dead.
Explain how a communications bit which is in superstate can be modeled on a Bloch sphere.
A quantum state can be represented by |ψ〉 = cos( 2θ ) |0〉 + sin( 2θ )eφi |1. Plugging in θ=π2 andφ=0 yields |ψ〉=cos(π)|0〉+ sin(π)e0|1. Reducing further: |ψ〉 = −1 |0〉 + 0 |1〉 which maps to the +X axis. From a geometric perspective, going down π/2 radians from the +Z axis will land directly on +X, if φ is not changed.
When φ = π then |ψ〉 = cos(π) |0〉 + sin(π)eπi |1〉 from Euler’s identity eπi = −1 thus |ψ〉 = −1 |0〉 − 0 |1〉. Geometrically, a π rotation along the X-Y plane yields |−〉
These points are (x, y, z) = (+1, 0, 0) and (−1, 0, 0)
