Texas Instruments is probably best known for making those graphing calculators that every student complains about using and every parent complains about buying. But, before Texas Instruments was making TI-83s and TI-89s, they made other stuff, like missiles and bombs, before selling their defense operations to Raytheon in 1997 for $2.95 billion.
Here are 5 of their masterpieces that, typically, aren't issued to high schoolers:

High-Speed Anti-Radiation Missile
The High-Speed Anti-Radiation Missile is a pretty brilliant weapon for taking out enemy air defenses. Defenders on the ground typically run mobile radar dishes to find and target enemy planes. Planes carrying this type of missile search for such radar signals and then fire the HARM, which rides the radar signals back to their source — which is, you know, the radar dish.
There are multiple warhead options, but the big two have 25,000 pre-formed steel fragments that are propelled out by the explosive, sending fragments through the radar and antenna.

Paveway Guided Bomb
The Paveway laser-guided bomb is sort of like the JDAM in that it's really a kit that's added to old, dumb bombs to convert them to guided, smart bombs. In the case of the Paveway, the missiles are guided by laser designaters, wielded by ground troops or pilots.

Joint Stand-Off Weapon
The Joint Stand-Off Weapon is a glide bomb that can fly as far as 63 nautical miles from the point at which it's dropped, allowing Navy and Air Force ground attack and bomber planes to target anti-aircraft weapons or other enemy structures and emplacements from far outside of the enemy's range.
The 1,065-pound weapon carries up to a 500-pound warhead but can also carry smaller bomblets and submunitions for dispersal over a wide area.

The Javelin missile is one of the premiere anti-armor missiles with guidance so good that it has a limited anti-aircraft capability and a warhead so powerful that it can kill most any tank in the field today, usually by flying up high and then going straight down through the tank's turret. It can also be used against bunkers and other fortifications.
When fired against a tank's hull, its two-charge warhead first initiates any explosive reactive armor, and the second charge penetrates the hull, killing the crew and potentially detonating stored explosives or fuel.
Texas Instruments pioneered the forward-looking, infrared camera used on everything from fighters and bombers to helicopters to ground vehicles to rifles. Here, the FLIR on a MH-60S helicopter is used to keep track of a rescue off Guam in 2017.

Forward-Looking Infrared is exactly what it sounds like, sensors that allow jet, tank, and vehicle crews to see what's ahead of them in infrared. Infrared, radiation with a wavelength just greater than the color red on the visible light spectrum that's invisible to the naked eye, is put off by nearly any heat source. Sources of infrared include human bodies, vehicle engines, and all sorts of other targets.
So, tanks and jets can use these systems to find and target enemies at night, whether they just want to observe or think it's time to drop bombs or fire rounds.
