TLDR: Clementino Mendes Pedrosa, 41, is a Sergeant-Adjutant in the Portuguese Army with 22 years of continuous service, including time in the Paratroopers, a Kosovo peacekeeping deployment, an Afghanistan tour, a 2017 deployment to the Central African Republic under UN mandate, and a decade as a survival instructor for the elite Comandos.
He has published two survival books under his tactical codename “SINISTRO” and is the first Portuguese contestant on Alone. Through Episode 4 he remains active and psychologically composed.
Clementino Pedrosa enlisted in the Portuguese Army in 2004 at age 19 and has not stopped since.
Twenty-two years later he is a Sergeant-Adjutant, the senior NCO rank in the Portuguese infantry, with deployments across three continents and a survival teaching career that has produced two published books.
He brings a tactical codename, Sinistro, earned during his 2017 UN deployment to the Central African Republic.
He is also the first Portuguese citizen to appear on Alone, which has generated considerable national attention in Portugal and a dedicated following on the country’s Reddit communities.
Twenty-Two Years in the Portuguese Army
Pedrosa began in the Paratroopers, serving as an enlisted soldier until 2009. During that period he deployed to Kosovo from 2006 to 2007 under the NATO-led Kosovo Force peacekeeping mission.
He then attended the Army’s Sergeant School for two years before being inducted into the Comandos on October 14, 2011.
The Comandos are headquartered at the Regimento de Comandos in Sintra and belong to Portugal’s Rapid Reaction Brigade.
Their doctrine emphasizes direct action raids, unconventional warfare, long-range reconnaissance, and counter-terrorism operations in small, isolated units, comparable in international standing to the US Army’s 75th Ranger Regiment.
Their motto, Audaces Fortuna Juvat, translates as “Luck Protects the Bold.”
The unit was originally formed in Angola in 1962 during the Portuguese Colonial War to counter asymmetric guerrilla campaigns, operating in groups of 20 to 30 men with aggressive forward doctrine.
That history of small-team isolation and self-sufficiency is embedded in how the Comandos train and think.
After his induction, Pedrosa deployed to Afghanistan under ISAF and to the Central African Republic in 2017 under the UN’s MINUSCA stabilization mission.
It was in the CAR that his operational team gave him the codename Sinistro, which he has used professionally ever since. On January 1, 2024, he was promoted to Sergeant-Adjutant, the top NCO rank in the Portuguese infantry.
Military Survival vs. Civilian Bushcraft
Pedrosa spent approximately a decade teaching survival within the Comandos framework, which means his training background is SERE (Survival, Evasion, Resistance, and Escape) rather than civilian bushcraft.
The distinction matters. Civilian survival assumes a permissive environment: build a visible shelter, burn an open fire, alter the landscape as needed.
Military survival assumes the opposite.
A survivor in a SERE context operates under the assumption that they may be actively hunted, which means building low-profile structures, burning small smokeless fires using techniques like Dakota fire pits, and leaving a minimal footprint.
Psychological conditioning for interrogation resistance and physical deprivation is also built into the curriculum in ways civilian courses do not attempt.
He has written about these differences in his two published books: PK SAFAMOS? (2020), which frames survival as an ancestral psychological state rather than a technical skill set, and 100 Habilidades no Desconhecido (2022), a practical 100-step illustrated guide for both military personnel and civilian outdoor practitioners, published by Atlantic Books Portugal.
His Strategy on Season 13
Pedrosa was dropped at coordinates 68°2’10.1″N, 135°20’25.2″W in the Richardson Mountains.
His most unusual gear choice was substituting a heavy-duty custom knife for the standard multitool, with stated intent to lash it to a shaft as , a bear spear, a decision that drew criticism from analysts who felt he sacrificed the multitool’s precision capabilities for a function his axe could partially cover.
His shelter is a sod house built from unpeeled logs with moss chinking and a tarp sealed over the top, a well-insulated structure with one documented vulnerability: he built it in an open area away from tree cover, leaving it exposed to wind chill and snow loading as winter deepens.
Every other contestant who experienced early difficulties from exposed positioning has had to address this mid-campaign.
On Day 11 a snare broke, a small equipment failure. Within the same day he killed a ptarmigan by hand-throwing a stick, adapting immediately without visible distress.
That sequence, problem then response then resolution, tells you something about how he processes setbacks.
Like Will Longley, he deliberately left family photographs at home, reasoning that emotional anchors of that kind create psychological liabilities in deep isolation rather than motivational resources.
Through Episode 4 he has maintained a calm, controlled demeanor that is consistent with his written philosophy: survival is an internal state managed through primal instinct, not an emotional struggle against external conditions.
