Expand the MARCH acronym

M - Massive bleeding

A - Airways

R - Respiration

C - Circulation

H - Hypothermia and other injuries

100

Filtration vs purification for water treatment?

Filter: Physically strains out protozoa and bacteria

Purification: Kills microbes directly

100

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"

100

What information does a declination diagram provide?

Angular relations between true north, grid north, and magnetic north. 

100

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

200

Four critical areas of detection on the human body?

Head, shoulders, waist and ankles.

200

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.

200

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.

200

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

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.

The algorithm to set your bezel for a heading during night land navigation?

Less than 180 -> Divide by 3. Move bezel counter clockwise. 

More than 180 -> Subtract from 360 and divide by 3. Move bezel clockwise. 

300

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.

400

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

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

400

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.)

500

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)
