NOTE: The Services feel that they must have tour (4) each, as an irreducible minimum. However, 

it was decided that eight (8) wou1d be a better figure, since this quantit7 would perin.it 

each service to conduct testing in several different locatiuns simultaneousl;r and lrould 

thereby reduce the total ti~ required for testing.
