P2 Mk2 Anti-Personnel Blast Mine
Overview
The P2 Mk2 is a small, pressure-activated anti-personnel blast mine manufactured by Pakistan. As one of Pakistan’s earliest indigenous plastic anti-personnel mine designs, it established the foundation for the country’s landmine production capability during the Cold War era. Like its sibling the P4 Mk1, the P2 Mk2 features minimal metal construction and serves a dual-purpose role as both a standalone anti-personnel weapon and as the initiating fuze for Pakistani anti-tank mines. The mine’s widespread proliferation to conflict zones across Asia and Africa has made it a significant humanitarian demining challenge.

Hazards
Primary Hazards
- Blast Effect: Produces an upward-directed blast causing severe traumatic injury to the foot and lower leg
- Injury Profile: Designed as a “maiming” weapon; typically causes traumatic amputation, compound fractures, and extensive soft tissue damage to the activating limb
Sensitivity Considerations
- Activation Pressure: Approximately 5-10 kg (11-22 lbs) of applied force
- Fuze Type: Simple pressure-activated mechanical fuze
Detection Challenges
- Minimal Metal Content: Constructed almost entirely of plastic; contains only a tiny metal spring or firing pin
- Detection Difficulty: Extremely difficult to locate with standard electromagnetic induction metal detectors
- Post-1997 Versions: Detectable versions with steel detection discs have been produced since 1997; existing stocks have been retrofitted to comply with CCW Amended Protocol II
UXO Considerations
- Long-Term Stability: Plastic construction provides weather resistance but may degrade over extended periods
- Armed vs. Safe: Mines with the plastic safety cap removed should be considered armed
- Environmental Factors: May become more sensitive due to degradation of internal components over time
Kill/Injury Radius
- Blast Effect: Localized blast affecting the activating limb; no fragmentation hazard
- Bystander Risk: Limited; non-fragmenting design minimizes collateral injury

Similarity to P4 Mk1
The P2 Mk2 and P4 Mk1 are externally very similar and may be nearly indistinguishable without detailed examination. Both share the same general dimensions, color scheme, and construction approach. Field identification should treat both types identically for safety purposes.
Fuzing Mechanisms
Fuze Type
- Primary Fuze: Integral mechanical pressure fuze
- Category: Direct-action fuze with no arming delay
Arming Procedure
- Remove the plastic safety cap from the pressure plate
- Emplace the mine in the ground (surface-laid or buried)
- The mine is now armed and sensitive to pressure
Functioning Sequence
- Pressure Application: A foot or weight applies 5-10 kg of force to the pressure plate
- Shear Wire Rupture: The internal shear wire breaks under the applied load
- Firing Pin Release: The spring-loaded firing pin is freed from restraint
- Detonator Initiation: The firing pin strikes the stab detonator
- Booster Ignition: The detonator flash initiates the booster charge
- Main Charge Detonation: The booster detonates the main explosive fill, producing the blast effect
Safety Mechanisms
- Safety Cap: Prevents accidental depression of the pressure plate during handling, transport, and storage
- Shear Wire: Provides a mechanical threshold ensuring the mine does not function under light pressure
Neutralization Methods (Qualified Personnel Only)
- Safety Cap Replacement: Carefully replace the plastic safety cap to render the pressure plate inoperative
- Detonator Removal: Unscrew the base and remove the detonator/booster assembly to break the explosive train
History of Development and Use
Development Background
The P2 Mk2 appears to be one of Pakistan’s first indigenous plastic anti-personnel mine designs, developed during the Cold War as part of the nation’s effort to establish domestic defense manufacturing capability. Pakistan Ordnance Factories (POF) was founded in 1951 with British technical assistance, and by the 1960s-1970s had expanded into landmine production. Early Pakistani AP mines were likely modeled after NATO and Warsaw Pact blast mine designs from the 1950s-1960s period.
Production and Export
Pakistan Ordnance Factories began mass-producing the P2 Mk2 and related mines by the 1970s. By the 1990s, POF was manufacturing at least six types of anti-personnel mines. Prior to international pressure in the late 1990s, Pakistan was considered one of the most prolific exporters of landmines to conflict zones worldwide, with Pakistani mines transferred through official military sales, covert supply channels, and third-party re-transfers.
Combat Employment
- Indo-Pakistani Wars: The P2 Mk2 was in service by the 1971 Indo-Pakistani War and was used to establish defensive minefields along the border and Line of Control
- Kashmir: Pakistani mines have been documented along portions of the Line of Control in disputed Kashmir territory
- Soviet-Afghan War (1980s): Pakistan supplied mines to Afghan mujahideen forces; some Pakistani border bases in FATA were also mined against potential Soviet incursions
- Kargil Conflict (1999): Reports of Pakistani mines recovered by Indian forces in Kashmir with POF markings
- Sri Lankan Civil War: P2 Mk2 and P4 series mines encountered by both Sri Lankan government forces and LTTE rebels
- Africa: Documented in Somalia, Eritrea, Ethiopia, Angola, and Tajikistan through various transfer mechanisms
International Restrictions and Compliance
Following the 1997 Mine Ban Treaty (Ottawa Convention) and amendments to the Convention on Conventional Weapons Protocol II, Pakistan implemented changes to its mine production:
- Since 1997, only detectable versions of minimum-metal mines have been produced
- Existing stockpiles have been retrofitted with steel detection discs
- Pakistan has not signed the Ottawa Convention but has modified practices to comply with CCW requirements
Current Status
- Production: Continues in detectable version form
- Legacy Contamination: Pre-1997 non-detectable mines remain emplaced in multiple contaminated areas worldwide
- Demining Priority: Represents a significant challenge for humanitarian demining operations due to minimal metal content

- Vehicle pressure (180-300 kg) collapses the AT mine pressure plate onto the P2 Mk2
- The P2 Mk2 detonates, initiating the AT mine’s main charge
- This system is used with P2 Mk2 (AT), P2 Mk3, and P3 Mk2 anti-tank mines
Frequently Asked Questions
Q: What is the difference between the P2 Mk2 anti-personnel mine and the P2 Mk2 anti-tank mine? A: Despite sharing the same designation, these are entirely different munitions. The P2 Mk2 AP is a small disc-shaped anti-personnel blast mine approximately 70 mm in diameter. The P2 Mk2 AT is a much larger square-cased anti-tank mine measuring 270 mm wide and 130 mm high. Confusingly, the P2 Mk2 AP mine can be used as the initiating fuze inside the P2 Mk2 AT mine. Context and physical description are essential for distinguishing between them.
Q: How does the P2 Mk2 compare to the US M14 “Toe-Popper” mine? A: Both mines share the same tactical role as small, minimal-metal anti-personnel blast mines designed to cause disabling foot/leg injuries. The M14 is slightly smaller (56 mm diameter vs. 70 mm) and cylindrical rather than disc-shaped. Both contain approximately 29-30 grams of Tetryl explosive and operate at similar pressure thresholds. Both present significant detection challenges due to their minimal metal content.
Q: Why are minimal-metal mines like the P2 Mk2 particularly problematic for demining? A: Humanitarian demining operations traditionally rely on electromagnetic induction metal detectors to locate buried mines. Mines constructed primarily of plastic, with only tiny metal components, produce minimal or no detector response, making them extremely difficult to find. Deminers must rely on alternative techniques such as prodding, ground-penetrating radar, or infrared detection, all of which are slower and less reliable. This significantly increases the time, cost, and danger of clearing contaminated areas.
Q: Can the P2 Mk2 be used as a booby trap? A: While the standard P2 Mk2 does not incorporate anti-handling features, its use as an initiator inside Pakistani anti-tank mines creates a de facto booby-trap situation. The AT mines (P2 Mk2 AT and P3 Mk2) have secondary fuze wells on the bottom that can accept anti-handling devices, and a GLM-2 electronic booby trap can be fitted to the cavity under the pressure plate. Any mine should be assumed potentially booby-trapped until proven otherwise by qualified EOD personnel.
Q: Where is the P2 Mk2 most commonly encountered today? A: The P2 Mk2 has been documented in numerous countries: Afghanistan (legacy of Soviet-Afghan War and subsequent conflicts), along the India-Pakistan border and Line of Control, Sri Lanka (civil war contamination), and several African nations including Angola, Somalia/Somaliland, Eritrea, and Ethiopia. Tajikistan has also reported presence of these mines. Active demining programs continue in many of these areas.
Q: What does the yellow band on the mine indicate? A: The yellow band marks the junction where the top and bottom halves of the mine body are joined. It is a manufacturing feature common to both the P2 Mk2 and P4 Mk1 mines and serves as a useful identification characteristic. The band does not indicate any special status such as practice/training variant or specific explosive fill.
Q: How should deminers approach suspected P2 Mk2 mines? A: Due to the minimal metal content, visual detection and careful prodding are often the primary location methods for P2 Mk2 mines. Once located, standard demining procedures apply: the mine may be neutralized by replacing the safety cap (if available) or by carefully removing the detonator/booster through the base. However, the possibility of degradation, anti-handling devices, or damage means that destruction in place is often the preferred disposal method. Only qualified demining personnel should attempt any intervention.
Q: What changes were made to the P2 Mk2 after 1997? A: Following international pressure and CCW Amended Protocol II requirements, Pakistan began producing only “detectable” versions of the P2 Mk2 and related mines. These incorporate steel detection discs that can be reliably located by standard metal detectors. Additionally, existing stockpiles have been retrofitted with metal detection aids. However, mines laid before 1997 remain largely undetectable, and these legacy items continue to pose the greatest humanitarian risk.
