Air gun
An air gun (or airgun) is any kind of gun that launches projectiles pneumatically with compressed air or other gases that are pressurized mechanically without involving any chemical reactions, in contrast to a firearm, which relies on an exothermic chemical oxidation (deflagration) of combustible propellants to generate propulsive energy.

Joint Light Tactical Vehicle
The Joint Light Tactical Vehicle (JLTV) is a United States military (specifically U.S. Army, USSOCOM, and U.S. Marine Corps) program to part-replace the Humvee with a family of more survivable vehicles with greater payload. The JLTV program was approved in 2006 to begin early studies. The JLTV program incorporates lessons learned from the earlier and now halted Future Tactical Truck Systems (FTTS) program and other associated efforts. JLTV has evolved throughout various development phases and milestones but variants are capable of performing armament carrier, utility, command and control (shelter), ambulance, reconnaissance and a variety of other tactical and logistic support roles. JLTV complies with the US Army's Long Term Armor Strategy (LTAS). The JLTV program (including numbers required and pricing) evolved considerably as the program developed. Oshkosh's L-ATV was selected as the winner of the JLTV program on 25 August 2015 and awarded an initial production contract for up to 16,901 JLTVs.

MOSFET
MOSFET showing gate (G), body (B), source (S) and drain (D) terminals. The gate is separated from the body by an insulating layer (white). surface-mount packages. Operating as switches, each of these components can sustain a blocking voltage of 120nbspvolts in the ''off'' state, and can conduct a continuous current of 30 amperes in the ''on'' state, dissipating up to about 100 watts and controlling a load of over 2000 watts. A matchstick is pictured for scale. A cross-section through an nMOSFET when the gate voltage ''V''GS is below the threshold for making a conductive channel; there is little or no conduction between the terminals drain and source; the switch is off. When the gate is more positive, it attracts electrons, inducing an ''n''-type conductive channel in the substrate below the oxide, which allows electrons to flow between the ''n''-doped terminals; the switch is on. Simulation result for formation of inversion channel (electron density) and attainment of threshold voltage (IV) in a nanowire MOSFET. Note that the threshold voltage for this device lies around 0.45 V The metal-oxide-semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon.
