Sadly, times have changed. The modern Easter Bunny must, in addition to route-planning and load balancing, contend with speeding lorries, hypoglycemic feral youths, and suburban professionals who've watched one too many Ray Mears specials. Still, the Eggs Must Get Through, and so the modern bunny must be able to defend itself.
The Tactical Rabbit Defence Plan is a two-pronged approach. In the first instance, Bunnies are advised not to travel alone. Instead, they are deployed in groups, increasing the chances of intimitdating or defeating an attacker and, in the last resort, allowing one or more Bunnies to escape with the cargo. Each unit is referred to as a Wrack of Wrabbits.

Secondly, each bunny is equipped with a Frickin' Laser on it's Forehead.
The Battle Bunny is still, clearly, in a prototyping phase, and there are a number of technical issues to be overcome. Beam power is currently inadequate for purposes other than highlighting an attacker's complexion in an unflattering colour. Additionally, firing the weapon currently requires someone to stand behind the bunny and press the button, which could be tactically limiting in close quarters engagements.
Also, they're made out of chocolate, and the R&D team keep eating the subjects. NOM!
