ARMA 2

ARMA 2 is a military simulation video game for Microsoft Windows, developed by Bohemia Interactive. It is the sequel to ARMA: Armed Assault (ARMA: Combat Operations in North America), and preceding ARMA 3. ARMA 2 saw a limited release in May 2009, and a wide release from June 2009 through July 2009. An expansion pack titled ARMA 2: Operation Arrowhead was released in 2010. In June 2011, a free version of the game was released, featuring multiplayer and limited single player modes. It is also considered the official successor of Operation Flashpoint: Cold War Crisis (under the title ARMA: Cold War Assault by Bohemia Interactive).

The game had sold 2.3 million copies as of February 2015.

Gameplay

ARMA 2 is a tactical shooter focused primarily on infantry combat, but significant vehicular and aerial combat elements are present. The player is able to command AI squad members which adds a real-time strategy element to the game. This is further enhanced by the high command system, which allows the player to command multiple squads using the map. ARMA 2 is set primarily in the fictional Eastern European nation of Chernarus (meaning "Black Rus"). The Chernarussian landscape is based heavily on the Czech Republic; the home country of the developer.

Fractional part

The fractional part of a non‐negative real number is the excess beyond that number's integer part: . Here is the largest integer not greater than x, the floor of x. For a positive number written in a conventional positional numeral system (such as binary or decimal), the fractional part equals the digits appearing after the radix point. Equivalently, it equals the original number with the digits before the radix point substituted with 0.

There are various conflicting ways to extend the fractional part function to negative numbers. It is either defined as (Graham, Knuth & Patashnik 1992), as the part of the number to the right of the radix point, (Daintith 2004), or as the odd function:

Here, is the smallest integer not less than x, the ceiling of x. For example, the number −1.3 has a fractional part of 0.7 according to the first definition, 0.3 according to the second definition and −0.3 according to the third definition.

Under the first definition all real numbers can be written in the form where is the number to the left of the radix point, and the remaining fractional part is a nonnegative real number less than one. If is a positive rational number, then the fractional part of can be expressed in the form , where and are integers and . For example, if x = 1.05, then the fractional part of x is 0.05 and can be expressed as 5 / 100 = 1 / 20.

The Marine Expeditionary Unit (MEU) is a Marine Air Ground Task Force (MAGTF) with a strength of about 2,200 personnel. The MEU consists of a command element, a reinforced infantry battalion, a composite helicopter squadron and a combat logistics battalion. The 15th MEU is currently based out of Marine Corps Base Camp Pendleton, California.

Mission

The mission of the MEU is to provide geographic combatant commanders with a forward-deployed, rapid-response force capable of conducting conventional amphibious and selected maritime special operations at night or under adverse weather conditions from the sea, by surface and/or by air while under communications and electronics restrictions.
