History of the P.I.A.T.
At
the beginning of the Second World War, British soldiers used the
anti-tank rifle "Boys" Mk I, offering a low rate of
fire and which could not pierce below 10 mm thick armor.
British military engineers, including Jeffries and Wallis, decided
to develop a new weapon in order to strengthen the possibilities
of the British infantry tactics. Engineers combined the mortar
structure of the rocket launcher technology and the firing device
of the anti-tank rifle "Boys" Mk I: the result was called
PIAT (Projectile Infantry initial Anti-Tank).
Some problems were identified by the infantry, which kept using
the PIAT throughout the Second World War. Thus, the trigger could
be operated only by using four fingers of the hand and the ammunition
used had to be handled very carefully, lest explode fast enough.
