22 of 50 cards from the Military Knowledge, Current Affairs and Awareness deck — real questions with worked answers.

1. What is the standard size and command rank of an infantry platoon in the British Army?

   A platoon has roughly 25–30 soldiers, is commanded by a Lieutenant or Second Lieutenant (a junior officer), and is supported by a Platoon Sergeant. It is typically made up of three sections of about 8 soldiers each.

2. List the British Army's main ground formations in order from smallest to largest.

   Section (8–10) → Platoon (~30) → Company (~100–120) → Battalion/Regiment (~600–700) → Brigade (several thousand) → Division → Corps. (A Field Army is the largest national formation.)

3. What are the key responsibilities of a platoon commander?

   Lead and motivate the platoon; plan and deliver tactical operations; ensure training, discipline, welfare and administration; make decisions under pressure; and act as the link between the soldiers and higher command. They hold legal and moral responsibility for those they lead.

4. State the British Army commissioned officer rank structure from lowest to highest (field ranks).

   Second Lieutenant → Lieutenant → Captain → Major → Lieutenant Colonel → Colonel → Brigadier → Major General → Lieutenant General → General → Field Marshal.

5. State the British Army's principal non-commissioned (other ranks) progression.

   Private → Lance Corporal → Corporal → Sergeant → Staff/Colour Sergeant → Warrant Officer Class 2 (WO2) → Warrant Officer Class 1 (WO1, e.g. Regimental Sergeant Major).

6. What is the difference between a command appointment and a rank?

   A rank denotes seniority and pay (e.g. Major), whereas a command appointment is the role/post held (e.g. Company Commander, Commanding Officer). An officer of a given rank fills an appointment; the same rank can hold different appointments.

7. Name the combat arms of the British Army.

   The teeth arms that close with and engage the enemy: the Infantry, the Royal Armoured Corps (armour/cavalry), and the Army Air Corps. The Royal Artillery and Royal Engineers are often grouped as combat support.

8. What is the distinction between combat arms, combat support and combat service support?

   Combat arms do the fighting (Infantry, Armour). Combat support directly assists the fight (Artillery, Engineers, Signals, Intelligence). Combat service support sustains the force (Logistics/RLC, Medical/RAMC, REME, Adjutant General's Corps).

9. What is the role of the Royal Artillery (Gunners)?

   To provide indirect and direct fire support, air defence and surveillance/target acquisition. They deliver firepower with guns, rocket systems (e.g. MLRS) and assist with finding and striking the enemy at depth. Motto: 'Ubique' (Everywhere).

10. What is the role of the Corps of Royal Engineers (Sappers)?

    To provide mobility (bridging, breaching), counter-mobility (obstacles, demolitions), survivability (fortifications), and general engineering and infrastructure support, including bomb disposal and water/power supply.

11. What is the role of the Royal Logistic Corps (RLC) and REME?

    The RLC supplies, transports and distributes everything an army needs (ammunition, fuel, food, equipment) and handles bomb disposal. REME (Royal Electrical and Mechanical Engineers) maintains, repairs and recovers equipment to keep it operational.

12. What is the primary role of the British Army within UK Defence?

    To protect the UK's interests by being able to fight and win on land, deter aggression, support allies, and provide a persistent presence. It generates land power and contributes to homeland resilience and Military Aid to the Civil Authorities (MACA).

13. Name the three single services of the UK Armed Forces and their core domains.

    The British Army (land), the Royal Navy including the Royal Marines (sea/maritime), and the Royal Air Force (air and space). Together they operate jointly under UK Strategic Command across domains.

14. What is UK Strategic Command (formerly Joint Forces Command)?

    A joint command that delivers and integrates capabilities used across all services — including cyber, intelligence, special forces oversight, medical, logistics and digital — enabling multi-domain integration alongside the three single services.

15. What is a 'standing commitment' for the British Army? Give examples.

    An enduring, continuous task the Army must always resource. Examples include the defence of the UK and Overseas Territories (e.g. Cyprus, Falklands, Gibraltar), public duties/ceremonial, support to the civil authorities, and contributions to NATO readiness.

16. What was Operation SHADER?

    The codename for the UK's military contribution to the Global Coalition against Daesh/ISIS, principally in Iraq and Syria — including air strikes, training of local forces and support — running from 2014 onwards.

17. What was Operation INTERFLEX (and its predecessor)?

    The UK-led programme to train Ukrainian Armed Forces recruits on British soil following Russia's 2022 invasion. It followed Operation ORBITAL (2015–2022), which had trained Ukrainian forces before the full-scale invasion.

18. What is Operation CABRIT?

    The UK's contribution to NATO's enhanced Forward Presence (eFP), with British forces deployed to Estonia (and previously Poland) to deter Russian aggression on NATO's eastern flank.

19. When and why was NATO founded, and what is its founding treaty?

    NATO (North Atlantic Treaty Organization) was founded in 1949 by the North Atlantic Treaty (Washington Treaty) to provide collective defence against the Soviet Union and ensure transatlantic security. The UK is a founding member.

20. What does Article 5 of the NATO treaty state?

    Article 5 is the collective defence clause: an armed attack against one member is considered an attack against all, and each may take action — including armed force — to restore security. It has been invoked once, after the 11 September 2001 attacks on the USA.

21. What is NATO's Article 4?

    Article 4 allows any member to call for consultations whenever it feels its territorial integrity, political independence or security is threatened. It triggers discussion, not automatic military action.

22. What is NATO's collective defence spending guideline for members?

    Members agreed to aim to spend at least 2% of GDP on defence. At the 2023/2024 summits this was reaffirmed as a floor, and the 2025 Hague summit set a higher long-term ambition (a headline 5% of GDP target including broader security-related spending).
