Soldiers and commanders are usually stuck with whatever equipment the procurement officers and civilian leaders are willing to buy for them, sometimes forcing troops to go into combat with outdated and inferior equipment.
But sometimes, those "outdated" weapons are actually just perfect for the fight. Here are five times that a supposedly obsolete weapon system saved the lives of its users:
1. Bayonets in Afghanistan and Iraq

Bayonets, most often associated with fighting in the Civil and Revolutionary Wars, actually played a key role in battles during the modern Iraq and Afghanistan conflicts.
The most famous probably came in 2004 when 20 British troops were trying to push insurgents from a series of trenches. The fire from the U.K. vehicles was doing little and ammunition was running low, so the commander ordered his men to dismount and fix bayonets.
The British killed approximately 20 of the enemy with their bayonets at a cost of three men injured. Overall, the enemy lost 28 men in the fight.
4. Pretty much anywhere the A-10 has ever fought

The A-10 Warthog (or the Thunderbolt, if you're into that) has been "outdated" since 1973 when the Yom Kippur War saw low and slow close air support platforms like the A-4 Skyhawk slaughtered while fast and high-flying planes like the F-4 Phantom largely survived.
But the A-10, a low and slow platform, made its operational debut in 1976, three years after the Yom Kippur War supposedly closed the books on them. Despite that, the A-10 has fought and survived in a number of contested environments, most notably Iraq where it has twice been a key part of American forces breaking the back of armored and anti-aircraft ground forces.
In Afghanistan alone, A-10 pilots saved a Special Forces team from five ground assaults against them; conducted forward air control and numerous attack missions to ensure the success of an 8-hour, no notice mission to capture a senior enemy officer; and prevented an accidental fratricide event before annihilating Taliban forces at Jugroom Fort.
5. The Night Witches and their plywood biplanes

The women of Soviet Russia's 588th Night Bomber Regiment, the Night Witches, flew in plywood and canvas biplanes through the best defenses that Nazi Germany had to offer, conducting multiple bombing missions per night to break up attacks against Soviet ground forces.
Their planes, the Polikarpov U-2 biplane, were underpowered and outgunned compared to the Luftwaffe's modern air force. But the Night Witches used the biplanes to fly over German defenses nearly silently and drop bombs — they could only carry two at a time per plane — on Nazi positions.
