CHAPTERS
- 0:00 – 2:35
Kelsi Sheren’s background: family history, WWII, and why veterans stay silent
Lex and Kelsi open by discussing how WWII veterans (including their grandfathers) often avoid sharing painful stories. They explore why passing down human stories matters and how knowing your lineage can provide strength and perspective.
- •WWII veterans’ reluctance to talk as a form of protection
- •The value of oral history and intergenerational lessons
- •Pride, identity, and resilience drawn from family lineage
- •Kelsi’s early pull toward history through WWII
- 2:35 – 11:47
World War II as a case study in evil, mass civilian death, and human nature
They zoom out to the scale of WWII atrocities and the psychological puzzle of leaders like Hitler and Stalin. The conversation centers on how ordinary people can follow charismatic dictators and whether history could repeat itself.
- •Civilian casualty scale and the difficulty of comprehending it
- •Charismatic dictators vs. social conditions that enable them
- •Fascination with the follower psychology more than the leader
- •Echoes of WWII rhetoric today and the dilution of “Nazi/Hitler” labels
- 11:47 – 19:04
Starvation, North Korea (Yeonmi Park), and what trauma does to the mind
Lex connects family history of famine to modern stories like Yeonmi Park’s escape from North Korea. They discuss how starvation warps behavior, the complexity of “normalizing” abuse, and what hope costs psychologically.
- •Starvation as a uniquely terrifying human experience
- •Trauma layers: indoctrination, escape, and abuse after escape
- •The burden of hope: realizing suffering can intensify pain
- •Geopolitical realism: why “fixing” North Korea implicates China
- 19:04 – 22:38
Recruiting videos, military marketing, and the idea of “hardness”
A tangent about U.S. and Russian recruiting videos turns into a debate on military marketing, deception, and what kind of mindset soldiers need. Kelsi argues for tougher preparation paired with better mental health support.
- •Recruiting as marketing vs. honest depiction of service
- •Kelsi prefers Russia’s intimidating style over softer messaging
- •Physical readiness standards and the reality of combat demands
- •Mental health support as a prerequisite, not an afterthought
- 22:38 – 26:05
Sports, aggression, and early betrayal: taekwondo, rugby, and a coach’s crime
Kelsi describes an intensely competitive youth shaped by martial arts and contact sports, including a vivid rugby injury story. She then shares a formative betrayal: a revered coach imprisoned for statutory rape, fueling anger and distrust.
- •Competitive identity built through taekwondo and rugby
- •Graphic rugby injury and comfort around blood
- •Coach as a father-figure “god” and the shock of criminality
- •Anger as a long-term driver after betrayal
- 26:05 – 28:58
9/11 from Canada: first brush with global conflict and social backlash
Kelsi recalls watching 9/11 at age 11 in Ontario and not fully grasping the magnitude until seeing others’ reactions. She notes immediate social consequences, including fear affecting Middle Eastern families, and her impulse to memorialize through a poem.
- •Vivid memory of the second plane impact and her mother’s reaction
- •School environment and the disappearance of Middle Eastern classmates
- •Early urge to “do something” despite limited understanding
- •Seeds of later engagement with war and conflict
- 28:58 – 36:02
Why she joined the military—and why artillery instead of infantry
Kelsi explains the gut-level moment she decided to enlist after feeling lost in college. She wanted a frontline role (infantry/armored/artillery), but being undersized steered her away from infantry and toward artillery’s reach and impact.
- •Remembrance Day and meeting a WWII female veteran as a catalyst
- •Leaving home, heartbreak, and searching for purpose
- •Infantry vs. armored vs. artillery roles explained in blunt terms
- •Size constraints, claustrophobia concerns, and choosing artillery
- 36:02 – 44:59
Artillery as the “Hand of God”: howitzers, rounds, precision, and forward observers
Kelsi dives into the mechanics and culture of artillery: the 155mm M777 howitzer, different types of rounds, and how precision is achieved via coordinates and forward observation officers embedded with infantry. She also describes the visceral experience of hearing artillery overhead and the emotional rush of delivering fire support.
- •M777 capabilities, range, and 100-pound rounds
- •Excalibur GPS-guided round and high-value targeting constraints
- •HE/illumination/shrapnel rounds and typical battlefield use
- •FOOs embedded with infantry; coordination to avoid friendly fire
- •The sensory experience: sound, ground-shake, fear, and adrenaline
- 44:59 – 52:40
Weapons training and the body cost: rocket launchers, rifles, grenades, and concussive blast
The discussion moves through Kelsi’s early exposure to small arms and heavy weapons, including the Carl Gustav launcher, C7/C8 rifles, and grenades. She also highlights long-term hearing and brain effects from repeated concussive blasts near artillery.
- •Carl Gustav and disposable launcher basics; backblast dangers
- •C7 vs. C8 ergonomics for smaller soldiers
- •Grenade mechanics and why they feel uniquely “primitive” and risky
- •Practical threats: grenades in Afghanistan’s close village corridors
- •CTE/hearing loss risk from repeated artillery concussion exposure
- 52:40 – 1:04:25
Rushed training and French-unit challenges: learning warfighting fast (and in another language)
Kelsi argues she wasn’t adequately trained for an active war, describing an accelerated pipeline from enlistment to deployment. Being posted to a French-speaking artillery unit added cognitive and social strain, even as a sergeant helped her adapt physically to the job.
- •Compressed timeline: 2007 enlistment → 2009 deployment
- •Learning technical radio/crew commands in French
- •Crew choreography: artillery as a symphony with roles and callouts
- •Adapting techniques for loading/operating given her height
- •“Shit pump” culture and the drive to be useful under pressure
- 1:04:25 – 1:19:36
Pre-deployment workups: Texas live-fire, Alberta field exercises, and Taliban tactics briefing
Kelsi recounts the ramp-up: artillery live-fire in Texas to simulate Afghan terrain, then extended workup training in Wainwright, Alberta with haptic engagement systems and role-played attacks. They discuss Taliban tactics such as IEDs, VBIEDs, and using civilians for concealment.
- •Texas live-fire as terrain/heat acclimation and crew-speed training
- •Wainwright workups: sleep deprivation, sentry duty, full kit routines
- •Simulation tech (haptics) and decision-based casualty outcomes
- •Taliban methods: IEDs, suicide bombers, concealment, civilian shields
- •Operational readiness vs. the reality of learning on the job
- 1:19:36 – 1:32:24
Arrival in Afghanistan: Kandahar’s surreal normalcy vs. FOB reality
Kelsi describes traveling through a stopover base to receive plates, weapons, and gear, then entering Afghan airspace where danger becomes real. Kandahar Airfield feels like a mini-city with fast food and gyms, but moving to a forward operating base shifts everything to austere conditions and constant readiness.
- •Stopover base: receiving armor, weapons, and first “real” kit weight
- •Tactical flight into Kandahar—first moment it truly hits her
- •Kandahar’s boardwalk amenities contrasted with war outside the wire
- •FOB purpose and structure: gravel-filled walls, towers, tents
- •Canadian artillery embedded inside an American-run FOB (Ramrod)
- 1:32:24 – 1:41:27
Small moments of humanity amid war: searching women, children, and the photo story
Kelsi shares a poignant story from an operation with British forces where she searched women and children and bonded briefly with a young Afghan girl. The moment of showing the girl her own photo reveals the shock of first-time technology and hints at suppressed hopes under oppression.
- •Role as a rare female searcher passed between units
- •Candy incident and protecting the girl from her brother’s violence
- •Taking a photo with a bright pink camera and showing it to her
- •Mother’s gesture (shaved legs) as a quiet sign of Western aspiration
- •How tiny human interactions echo long after combat ends
- 1:41:27 – 2:00:44
The tragic IED incident: first close death, collecting remains, and the “light switch” breaking
Kelsi recounts an IED blast that killed a soldier and triggered a chaotic firefight, mortars, and urgent extraction. She describes the dissociation, grim dark humor, and the desperate effort to recover a friend’s remains so they can’t be exploited for propaganda.
- •IED in a grape hut; contained blast with catastrophic results
- •Immediate escalation: comms chaos, KIA calls, incoming mortars
- •Dissociation and shock—humor about reusing a boot
- •Recovering remains under fire; fear of Taliban propaganda abuses
- •Black Hawk extraction and the abrupt transition to “deafening quiet”
- 2:00:44 – 2:08:22
Aftermath and moral injury: sensory triggers, survivor’s guilt, hatred, and losing humanity
The conversation turns to how the incident reshaped Kelsi’s mind and body—lasting sensory triggers (touching meat/skin), compulsive hand-rubbing, and profound survivor’s guilt. She also describes how hatred overtook empathy during the deployment, dehumanizing the enemy and sometimes civilians.
- •Trauma stored in the body: tactile triggers tied to human remains
- •Compulsive self-soothing behaviors under overwhelm
- •Survivor’s guilt: fixation on whether they recovered “all of him”
- •Hatred as adaptation: enemy no longer seen as human in the moment
- •PTSD roots in indistinguishable threats: civilians, objects, environment
- 2:08:22 – 2:28:15
Taliban strategy, why the war was unwinnable, and the 20-year Afghanistan retrospective
Lex presses on whether enemies are ‘brothers in arms,’ while Kelsi insists Taliban brutality and civilian shielding change the moral calculus. They debate how to fight radicalism, the limits of force, and the importance of education—especially girls’ literacy—while reflecting on the failures of withdrawal and political leadership.
- •Taliban blending into civilian life as a deliberate winning strategy
- •Force creates long-term hate; propaganda leverages civilian casualties
- •Education/literacy as the only durable path to cultural change
- •Critique of the withdrawal logistics (e.g., Bagram vs. civilian airport)
- •Anger at governments’ accountability gaps and abandonment of allies/vets
- 2:28:15 – 4:06:05
From war to recovery work: ‘Fucking Help Somebody’ and beginning the PTSD autopsy
Kelsi introduces the ethos behind her post-war mission—work hard, help harder—through a collaboration with GFDA and the message ‘Fucking Help Somebody.’ Lex then pivots into the psychological before-and-after, setting up a deeper exploration of PTSD, leadership failures, and what could have changed her trajectory.
- •Post-war identity anchored in service and lifting others
- •GFDA collaboration and the ‘Fucking Help Somebody’ message
- •Afghanistan as the experience that nearly destroyed her
- •Self-assessment: who she was before vs. after the pivotal trauma
- •Lead-in to PTSD specifics and the question of leadership intervention
