visual and audible signalling area and target illumination reference point marking indication of practice weapon impact or fuze action tracking decoying simulating jet engine starting smoke screen generation
In your own words the difference between direct and delay arming
Direct: Armed immediately upon the removal of a safety device
Delay: The fuse is armed after a pre determined time after arming initiation
