Science fiction weapons for the battlefield

Evan Haning, wtop.com

WASHINGTON — The RQ-170 Sentinel drone that Iran displayed last week uses technology that once existed only in science fiction. But now, almost anything weapons researchers can dream up seems possible.

Wired.com’s list of 10 sci-fi weapons that actually exist includes real world devices that perform like CGI on IMAX screens.

The XM-25 grenade launcher finds its targets with a laser rangefinder and locks on it using an on-board computer. Projectiles detonate as they pass their targets, striking enemies as they take cover. The Army hopes to provide at least one of these to every Special Forces unit and infantry squad by next year.

The Bedazzler is a vomit or seasick beam. It is a handheld, non-lethal device that uses flashing lights to upset equilibrium in its target. Its creators claim you can build one at home for less than $250.

The Active Denial System cooks water in its target’s skin with millimeter-wave radiation. People feel as if they are burning, but the “pain ray” causes no permanent damage, at least in theory.

The Long Range Acoustic Device has been used on foreign pirates and domestic protestors. It sends a narrow, ear-splitting sound beam like an audio spotlight as far as 1,000 feet.

Different drones do different things. The captured RQ-170 Sentinel evades radar, thanks to its stealth shape. Predators can observe for long periods of time without being seen. Reaper drones can hold four Hellfire missiles and two 500-pound bombs.

And just as the L-RAD has been used against domestic protestors, Predator drones have been deployed in North Dakota and along the U.S. border with Mexico.

Flash bang grenades are only supposed to stun, but — like tasers — have a less than perfect safety record. After accidents that dismembered at least one soldier and deafened several more, the improved Flash Bang Grenade eliminates the shockwave and creates its blinding flash by throwing aluminum particles in the air.

Instead of firing a warning shot, the LA-9/P fires a warning laser pointer. The Marines refer to these green laser pointers as “ocular interruption devices,” and they can send their beam 2.5 miles.

The Laser Avenger mounts on a hummer and its beam is at least 12,000 times stronger than the green warning laser. Boeing’s 1-kilowatt laser can bring down drones and destroy improvised explosive devices.

Northrop Grumman also develops laser systems, including solid-state lasers for maritime use.

Don’t Settle for Student Loans to Pay for Online Education

Online college programs are becoming a more popular choice for prospective students, with one study finding that more than 6 million students enrolled in at least one online course in fall 2015. The popularity of these courses can be attributed in part to their flexibility with working adults' schedules, students' ability to progress more quickly through online programs and, oftentimes, cheaper tuition. [See 10 low-cost online bachelor's programs for out-of-state students.]Online degrees can be beneficial to many college students, but some studies have shown online learners complete their programs at lower rates than students at traditional brick-and-mortar campuses. Individuals with student loans but no degree comprise two-thirds of defaulted borrowers. Though these numbers are not encouraging, just like for traditional programs, there are ways to reduce how much you'll need to borrow for an online program to ensure you won't become one of these statistics. Don't just settle on borrowing student loans to cover the whole cost of your program and living expenses. Instead, start thinking about how to cut costs and cover your balance in different ways, such as the following. -- Grants and scholarships: Even though you are taking an online course, you can still apply and receive grants and scholarships. But your first step should be to complete the Free Application for Federal Student Aid, commonly referred to as the FAFSA, which will allow you to receive a Pell Grant if your expected family contribution is low enough. The EFC criteria and award amounts are adjusted annually, but the 2017-2018 academic year awards range from $606 to $5,920, which could significantly lower the amount you borrow annually. Your next step is to apply for scholarships. You can start by checking online scholarship search engines, such as the Salt Scholarship Search, College Board's BigFuture and Peterson's. But don't forget to take advantage of local organizations and your school's financial aid office. Both may offer scholarships that you can't find with a national scholarship search. [Review these 10 sites to kick off your scholarship search.]For instance, organizations like the Elks Club, Knights of Columbus or the Rotary Club typically offer scholarships annually to local students. Just because you're going to school online doesn't mean you're ineligible. Visit your local library for scholarship listings, and ask around town. You might be surprised how many local organizations offer scholarships. While these scholarships typically aren't large, every little bit counts. Each dollar you receive in a scholarship is a dollar you don't have to borrow and pay interest on. -- Work-study: Another option for online students may be work-study awards. Not all students enrolled in online programs are eligible, but students at some schools -- including, for example, SUNY Empire State College and Liberty University -- are. Work-study awards are not given upfront like scholarships and grants. In most cases, they are an offer to earn up to the awarded amount if you secure an eligible work-study job. While there is a misconception that all work-study jobs must be on campus, students can work for off-campus, nonprofit or public employers as long as the work is in the public's interest. You may be able to work for a for-profit employer if the job is relevant to your course of study. No matter who the outside employer is, it will need to have an established agreement with your college for you to receive work-study funds. Remember, to be eligible for federal financial aid, you must be enrolled and pursuing a degree or certificate. If you're not working toward a credential, Pell Grants and work-study won't be option, but you may still be able to take advantage of private scholarships -- just be sure to read the eligibility criteria carefully. [Explore what to know about financial aid in online programs.]-- Pay as you go: One of the great benefits to enrolling online is the flexible schedule, which can allow you to complete your college coursework around your responsibilities. But prospective students often overlook using their part- or full-time job earnings as an option for paying for college. Almost 80 percent of college students in 2015 worked at least part time while attending classes, according to the National Center for Education Statistics. By budgeting and thinking strategically about your college costs, you can likely reduce your dependence on student loans by paying a portion out of pocket. Many -- but not all -- online programs are less expensive than traditional programs and often have shorter payment periods. Six, eight or 10 weeks are common course durations. Because of the frequency of payments in an online setting, you may be well-placed to pay as you go and possibly avoid borrowing altogether. Attending college online and avoiding student loans may be challenging, but if you are willing to put in the effort, you can limit the amount you need to borrow.
