One method is to have a flight planning section manned by a senior air craftsman or corporal who will filter the NOTAMs for his unit's mission. These will usually be plotted on a display board enabling a quick overview by a crew. They can then read the relevant details. Those for further afield will not be plotted but grouped by country or area.
For units not using a central briefing facility the local NOTAMs will be forwarded; for overseas flights they will be forwarded on request.
Many of the examples cited by High Spirits do indeed clutter a brief. A crew planning a high transit will skip over low level notifications except perhaps close to destination. Unlit obstructions are indeed 'noise' but thankfully rarely do they bite you. Notable ones are wire strikes, typically cables across Norwegian fjords and tragically the EA6 cable strike in Italy.
