Editing Warhammer 40,000/10th Edition Tactics/Tyranids (section)

===Swarms===
*'''Ripper Swarms:''' Never leave home without some if you take the Parasite of Mortrex (otherwise, ''always'' do - they're trash on their own). While they remain utterly pathetic, their annoying factor has dialed up some by making enemies engaged with them have their Objective Control halved; what cripples them as a unit is their OC 0.  What saves them with the Parasite is that they get delivered directly into melee near a model (the Parasite) that can potentially take the objective thanks to their OC debuff.
**Remember that the Core Rules simply do not address how to properly halve an odd number.
