Question:  The rapid anti-personnel minefield breaching system and Bangalore torpedo are both examples of explosive devices used to do what?

<P0-S0>  It is used by combat engineers to clear obstacles that would otherwise require them to approach directly, possibly under fire. <P0-S1> A Bangalore torpedo is an explosive charge placed within one or several connected tubes. <P0-S2>  It is sometimes colloquially referred to as a "Bangalore mine", "banger" or simply "Bangalore". <SEP> <P1-S0> The Mark 16 torpedo was a redesign of the United States Navy standard Mark 14 torpedo to incorporate war-tested improvements for use in unmodified United States fleet submarines. <P1-S1>  The torpedo was considered the United States standard anti-shipping torpedo for twenty years; although significant numbers of Mark 14 wartime production remained in inventory. <P1-S2>  This hydrogen peroxide propelled, 21 inch (53 cm) torpedo was 246 inches (6.25 m) long and weighed 2 tons (1800 kg). <P1-S3>  The Mod 0 warhead contained 1260 lb (572 kg) of TPX explosive and was the most powerful conventional submarine torpedo warhead ever used by any Navy. <P1-S4>  The United States used TPX explosive which was about 75% more powerful (7405 J/g.) <P1-S5>  than the Type 97 explosive in the larger Japanese Type 93 Mod 3. <P1-S6>  (780 kg of Type 97, 4370 J/g.) <P1-S7>  The Mod 1 warhead contained 960 lb (435 kg) of TPX or HBX (7552 J/g.) <P1-S8>  explosive. <P1-S9>  The torpedo could be set for straight- or pattern-running. <SEP> <P2-S0>  It is designed to replace the Bangalore torpedo, offering a more effective and flexible alternative. <P2-S1> The rapid anti-personnel minefield breaching system or RAMBS II is a British rifle grenade used to breach obstacles and clear minefields. <P2-S2>  When deployed, the RAMBS II will clear a path 60 metres long and 0.6 metres wide, compared to the Bangalore's cleared area that is 15 metres long and 1 metre wide. <SEP> <P3-S0> Pyroshock, also known as pyrotechnic shock, is the dynamic structural shock that occurs when an explosion or impact occurs on a structure. <P3-S1>  Davie and Bateman describe it as: "Pyroshock is the response of a structure to high frequency (thousands of hertz), high-magnitude stress waves that propagate throughout the structure as a result of an explosive event such as an explosive charge to separate two stages of a multistage rocket." <P3-S2>  It is of particular relevance to the defense and aerospace industries in that they utilize many vehicles and/or components that use explosive devices to accomplish mission tasks. <P3-S3>  Examples include rocket stage separation, missile payload deployment, pilot ejection, automobile airbag inflators, etc. <P3-S4>  Of significance is the survival and integrity of the equipment after the explosive device has activated so that the vehicle can accomplish its task. <P3-S5>  There are examples of flight vehicles Boeing-The Aerospace Corp which have crashed after a routine explosive device deployment, the cause of the crash being determined as be a result of a computer failure due to the explosive device. <P3-S6>  The resultant energies are often high "g"-force and high frequency which can cause problems for electronic components which have small items with resonant frequencies near those induced by the pyroshock.
