This concurs with the pre-M16A2 maximum effective range of 460 m (503 yd). [112] The Colt 3×20 telescopic sight was factory adjusted to be parallax-free at 200 yd (183 m). [ 113 ] [ 114 ] In Delft, the Netherlands Artillerie-Inrichtingen produced a roughly similar 3×25 telescopic sight for the carrying handle mounting interfaces.
Note *: The effective range of a firearm is the maximum distance at which a weapon may be expected to be accurate and achieve the desired effect. [ 168 ] Note **: The horizontal range is the distance traveled by a bullet, fired from the rifle at a height of 1.6 meters and 0° elevation until the bullet hits the ground.
Complementing the 16-in/50 caliber Mark 7 gun was a fire control computer, the Ford Instrument Company Mark 8 Range Keeper.

The conclusion of the board vis-a-vis corps (heavy field) artillery was that an ideal heavy howitzer should have range of at least 16,000 yards (15 km) and allow the elevation of 65° [2] (as opposed to the existing World War I-era M-1918 155 mm howitzers, a license-built French Canon de 155 C modèle 1917 Schneider, 11.5 km and +42° 20 ...
With the addition of clinometers fixed machine gun squads could set long ranges and deliver plunging fire or indirect fire at more than 2,500 m (2,730 yd). This indirect firing method exploits the maximal practical range, that is defined by the maximum range of a small-arms projectile while still maintaining the minimum kinetic energy required to put unprotected personnel out of action, which ...
Its maximum effective range is 3,000 m (3,300 yd). According to Jane's, the M829 is capable of penetrating 540 mm (21 in) of RHA steel armor at up to a 2,000 m (2,200 yd) range. [3] The original M829 is no longer in production and has been succeeded by the M829A1, M829A2, and M829A3. The corresponding training round is the M865, costing $1,121. [2]
