Missile Launcher Discovered On Jersey City Lawn?

Imagine my surprise if I were to discover a rocket launcher on my front lawn. Well, that's exactly what happened to a woman in Jersey City. She found an item that she initially believed to be a pipe on her lawn. However, on closer inspection, it was a missile launcher.

She called police, who are now investigating the matter.

A Jersey City woman made a shocking discovery on her lawn this morning when she noticed a military rocket launcher lying in the grass.

Niranjana Besai was leaving her house, located at 88 Nelson Street, to go to work just after 8 this morning when she spotted the launcher on her front lawn. "I read it and it [said] 'missile,'" Besai told CBS 2 HD. "There was little 'missile' [writing] on it."

She immediately called police.

Sources tell CBS 2 HD that the device is an AT-4 missile launcher that is used to fire against tanks and buildings. The device was first approved by the U.S. Army in 1985 and questions are being raised as to whether the device was stolen from a branch of the military.

What's more troubling, sources add, is that Besai's house is located along flight path for Newark Liberty International Airport.

Jersey City police were not saying whether the device was operative or not. If the device is indeed an AT-4 launcher, here's what one would look like and the specs.

UPDATE:
There are several weapons that are called AT-4. The weapon above is an antitank weapon of Soviet origin. This is an American weapon that is also designated an AT-4, and appears to be more in line with what is being described. The other weapon system is larger, heavier, and is more often mounted on a vehicle.

UPDATE:
Feds report that the launcher was harmless as it was empty. Still, there are questions to be asked as to how it arrived on this person's front lawn.

An empty military rocket launcher found on the front lawn of a Jersey City residence today caused a brief scare today, before federal authorities determined the device was inoperable and harmless.

U.S. Army ordinance experts are now trying to track down the serial numbers on the device to determine its origin.

According to the FBI, the launcher was the empty holder for an AT-4 anti-tank weapon - a one-shot rocket-propelled projectile used by the infantry to destroy or disable armored vehicles. The launcher is discarded after use.

UPDATE:
I deleted the image of the Soviet-make AT-4 as that is not the weapon involved here. Also, it appears that one could potentially purchase the AT-4 casing online for $250 (HT: easy at LGF).
