3.—(1) This paragraph shall apply when an allowance payable to the child of a serviceman in pursuance of paragraph (4) of Regulation I3 is increased in pursuance of paragraph (5) of that Regulation.
(2) The increased amount of the allowance payable to the child for any period shall not, when aggregated with the amount of any armed forces award payable to or for the child for that period in respect of the serviceman, exceed the amount of the allowance which would have been payable for that period if the injury as a result of which he had died had been treated as if it were an injury received without his own default in the execution of his duty as a regular policeman.
