How a simple metal tube setup can rain death on the bad guys

To an infantry squad leader, having the powerful tool of "mortars-on-station" gains allied forces a massive battlefield advantage. Setting up the weapon system can be fast and flawless with a well-trained crew.


A mortar tube is comprised of an elongated, closed metal tube mounted on a base plate.

On the bottom of the mortar tube is a fixed firing pin. Once a mortar shell is loaded and dropped into the tube, it slides down and strikes the firing pin which causes the mortar's propellant to ignite creating gas pressure — launching that sucker at the bad guys.

Simple, right? (Images via Giphy)

The mortar round itself is made up of several vital but straightforward parts.

Its main components are made up of the impact fuse at the top – which triggers the exploder – followed by the high-explosive filler in the central portion of the body.

The propellant charges are made up of two components: The primary charge and augmented charges — both located in the tail section.

The augmented charges can be added or removed based on the speed or range the mortarman wishes it to travel.

Modern mortars are designed to provide short-range indirect fire at high angles, typically between 45 and 80 degrees. They are relatively light-weight in nature making them more accessible to carry while on a foot patrol. It's much better than hauling a 155mm Howitzer artillery shell.

That sh*t is heavy.

In the event the bad guys do get "froggy," the mortarmen on the ground can quickly and efficiently set up the mortar system while the infantrymen accurately get a fix on the enemy's position and make it rain 81mm mortar — it's a beautiful spectacle.

Britain is no longer a 'tier one' military power

Theresa May asked Britain's defence secretary to justify the UK's role as a "tier one" military power, causing dismay in the Ministry of Defence. Underlying the statement is a realisation that the UK can no longer economically compete with top powers, defence experts told Business Insider.

"It's a reflection of our economic status — times are tough," said Tim Ripley, a defence analyst, adding: "It's all about money... if you don't have money you can't spend it."

The Prime Minister questioned defence secretary Gavin Williamson on whether money for the military should be reallocated to areas like cyber, and if Britain needed to maintain a Navy, Army, Air Force and nuclear deterrent all at once.

This Microsoft training fast tracks veterans into sweet tech careers

Solaire Brown (formerly Sanderson) was a happy, gung-ho Marine sergeant deployed in Afghanistan when she realized her military career was about to change. She was tasked with finding the right fit for her post-military life – and she knew she wanted to be prepared.

Injuries sustained during mine-resistant vehicle training had led to surgeries and functional recovery and it became clear Brown would no longer be able to operate at the level she expected of herself as a Marine.

Like many of the 200,000 service members exiting the military each year, Brown knew her military training could make her a valuable asset as an employee, but she was unsure of how her skills might specifically translate to employment in the civilian world.

Enter Microsoft Software & Systems Academy (MSSA), a program Microsoft started in 2013 to provide transitioning service members and veterans with critical career skills required for today's growing technology industry.

This video of a drone with a flamethrower will haunt your dreams

Watch the video in the tweet below. Are you experiencing both amazement and fear? You're not alone.

This video has been making the rounds on Twitter recently, but it was actually filmed a little over a year ago. According to Gizmodo, an electric-power maintenance company in Xiangyang, China, had been using these flame-throwing drones to burn off garbage and debris from electrical wires.

This band hires vets — especially when they go on tour

As veterans re-enter the civilian workforce, many struggle to make the transition. This is why opportunities (ahem — touring with famous heavy metal bands) for employment are so important. Five Finger Death Punch has made it a mission to offer such opportunities.

Soldiers at the border are doing grunt work to stay out of trouble

National Guard troops deployed to the border in Arizona are puttering around doing administrative and maintenance work in order to keep them out of potentially dangerous situations and to allow the border patrol to focus on working in the field.

Troops have been deployed to the border in the past — both Presidents George W. Bush and Barack Obama sent troops there under similar circumstances — but the ones currently stationed in Arizona are even farther from the border than past deployments, according to a Politico report, and have no involvement in law-enforcement activity there.

President Donald Trump has called for up to 4,000 troops from various states to deploy to the border from Texas to California. Only about 200 Arizona National Guard soldiers have been put to work there, less than one-third of the 682 who have been authorized to deploy.

This Brazilian trainer thinks it can replace the Warthog

Brazil has had a decent aerospace industry centered on Embraer, a conglomerate that made everything from airborne radar planes to trainers. However, that industry has gotten a little too full of itself lately. They think one of their trainers can replace the A-10.

Now to be fair, this trainer, the Super Tucano, is doing some attack work with the Afghan Air Force and is a contender in the Air Force's OA-X program, advancing to a fly-off with the AT-6. Two other contenders, the AT-802 and the Textron Scorpion, didn't make it to the fly-off. Stinks to be them, but honestly, could any of them really replace the A-10?

Here's how working out every day can save you money

It's no secret that service members don't make a whole lot of money compared to the intense workload they face every single day. Since this lack of funds can limit things we like to do during our days off, we have to find little ways to compensate our cash to make sure we pay our bills.

Every few weeks, veterans should sit down and create a budget plan and adequately manage their incoming cash flow. These charges typically account for rent, groceries, and entertainment. The costs add up quickly, and it doesn't feel like there's much left over to put in savings.

But what if we told you that you can save some real coin if you just decided to it start hitting the gym on a daily basis?

Would that potentially blow your mind?

Migrant children in the US might be moved to military bases

The Trump administration is considering housing up to 20,000 unaccompanied migrant children on military bases in coming months, according to lawmakers and a Defense Department memo obtained by The Washington Post.

In a notification to lawmakers, the Pentagon said that officials at the Department of Health and Human Services asked whether beds could be provided for children at military installations "for occupancy as early as July through Dec. 31, 2018."

Sen. Charles E. Schumer (D-N.Y.) addressed the issue on the Senate floor on June 21, 2018.
