Lmao imagine being a rebel trying to do fed or prison and the APD has a downing minigun quilin. Or youre a rebel trying to do shipping against APD 50 cals being spammed. You guys already cry about ifrits. If this happened, I could not imagine the amount tears that would be dropping in the suggestions and feedback part of the forums for the removal of these vehicles.
On top of this, the times when this would suck for the APD would be like @Sandwich said, when there is only constables on. Their 5.56 is doing absolutely nothing to a marid and they are just gonna get riped out 100% of the time making cop unplayable for them at events. I'd imagine not even Corporals are gonna get access to these armed vehicles.
