Army deploys the Pulse Rifle from Aliens

While technology has continued to advance in the areas of communication, computation, and large scale weapons (like nuclear weapons and drones), the humble rifle has remained largely unchanged since the Vietnam war. No longer. The army has announced the XM25 Counter Defilade Target Engagement System, a high powered rifle with programmable rounds that can be set to explode at any pre-set range.

It also has the advantage of looking like everyone's favorite prop from James Cameron's version of the Alien movies.
