A concentrated enemy is always cheaper to defeat than a dispersed enemy. Dispersion will force priority selection. Often less important priorities will be neglected entirely. If any attack is neglected by the defender, then that attack will always succeed. A defender with a limited defence capability will neglect all but the most important targets. Balance your total dispersion with localized concentration and you will always have force superiority where it matters.
When attacked by a greater force, disperse your force. Your enemy will either disperse his own force in an attempt to destroy your detachments or ignore your tactic entirely. Only re-concentrate your forces where you can have force superiority over his detachments. If your enemy does not disperse his force, then you must harrass his lesser defended assets to maintain his force’s moving from point to point in his own territory (rather than steam rolling through your assets). Even attacking with singular units on alternating sides of his force may cause him to halt his advance (while he eliminates your forces one at a time).
