Communications can come in many forms such as text, voice, and video and, for command and control purposes, their infrastructure must be in place and be as robust as possible, so as to preserve communication channels even in emergencies when some forms may be incapacitated and sufficient redundancy must be built in to cater for the loss of particular systems (e.g. telephony) or premises or a collapse due to excessive traffic (e.g. computer system or Internet crashes).
Er kan schriftelijk, mondeling en via videobeelden worden gecommuniceerd. Voor bevels- en controledoeleinden moet de infrastructuur zo robuust mogelijk zijn en moeten er in noodsituaties voldoende communicatiekanalen beschikbaar blijven, zelfs indien bepaalde gebouwen schade oplopen of bepaalde systemen uitvallen (bv. telefoon) of overbelast raken (bv. computersystemen of internet).
