Figure 2. Trench Bunker
Ordnance Bunkers:
The ordinance is a weapon of large cannonry guns ammunitions and missile launchers. Especially anti-ship artillery its historical actions of protected all-embracing bunkers systems [4]. That typically accommodated the group of squad operations of working weapons systems. Modern days weapons systems handled in fully electronic and hydraulic automation actions of counterattacked. Especially ammunition is prepared is dependent upon the site of the area of the bunkers. For examples of cold region, snow area is special ammunition weapon handled target. And long-range seashore areas, missile (short and long-range) and long-range air command anti-ballistic missiles, that types tactical weapons are handled in bunkers. Ordinance cannon bunkers are mass and entity in pre cold war bunkers. Dover strait coastal gun fixed provision in northern France were up to 3.5 m thick and beneath the bunkers. Is mechanical design productions for the V-3 multi charge cannon.
Types of weapons systems use in bunkers:
Bofors guns are the simplest and most powerful efficiency of land, water and air base defence power systems. Is working for autocannon designed in 1930 Swedish defence designed and manufacturer “AB Bofors”. Its services in 1930 to and for the most part popular weapons in currently services in 21st century’s. its high activations in all types of wars in WW 2, Indo- Pakisthan war conflicts, Korean, Vietnam, Gulf, south African border, Yugoslav, Yemeni civil, Yemen wars, Yom Kippur, Falklands, Lebanese Civil War, Saudi-led intervention in Yemen. Its typically used inland to air, land to water base, air to a land base and water ship base to land or air anti-aircraft attacks. Its 40 mm L/70 Bofors models are used by the ends of WW 2, tat model payload of ammunition is automatically [5]. And the speed of attack in jet aircraft. Its simplest Bofors gun Consequently has to long ranges higher rate of fire. And the efficiency of the integer of rounds fired the ended the period of rendezvous. Bofors designed updates of 40mm and alternative to making the 57 mm designed. It is most powerful for compared 40mm L/70. The new designed of 40mm is a larger 40 x 364R round firing. The shell weight is less than 1Kg and velocity of muzzle firing is 1030m/s. and rate of firing is 200 to 240 rounds/minutes [6]. Modern Bofors additional techniques to improvements of designed developments 300 rounds/minutes (5.56 rps). BAE systems C-ITC is Swedish acquired high-tech companies. Its includes innovators computer-based research replication and training technologies. Bantam (Rb 53) is also a model of Bofors missiles criteria lightweight anti-tank combating missiles, developed in the 1950s by Bofors.
0.53 Caliber Machine Gun:
M 2 browning gun [7] is a 53 calibre heavy machine gun (.53BMG) it designed models in world war 2, the designer name is john browning. It designed is the same First models M1919 (BMG) Browning Machine Gun. Which was a barrel for the 7.62mm ammunition are use M2 was more influential 50 BMG ammunition. Its development of updates in forename of the gun itself is standards for Browning Machine Guns. 50 calibre M2 browning machine gun is most flexibility in unarmored, and light armoured of vehicles in coast guard boats, attacking helicopters, and bunkers are majorly used. The 50 BMG is the late 1910s. entering by the C.I.P ammunition developed in the browning 50 machine gun in the late of 1910s. its heavy duties for the war of during WW 2, Korean, Vietnam, Falkland, etc. in the 2000s to 2010. Is a majorly used in the machines in NATO countries. And current M2HB is productions in the US general dynamics or US ordinance. Via foreign military scale. Specifications of BMG weight is 38 to 58 kg and used tripod traverse elevation mechanics. The total length of BMG is 1654 mm and the length of the barrel is 1143mm. 12.7x99mm NATO ammunition cartridges are fit for the gun. This operation is short recoiling-operated. 400 to 600 round/min and 750-800 round/min(AN/M2), 1200 – 1300 round/min (AN/M3). And muzzle velocity is 890m/s. long effective firing ranges (2500m) is long-range targets. M2 or M9 links belt loading systems. M2 BMG is the same visions of M1917 BMG using every time gauge.
Anti tank missile systems:
Anti Tank Missile is an (ATGMs) Anti guidance missile weapons systems [8]. It is designed to be primarily to hit the targets and destroyed the heavily armed defence vehicles. ATGMs is short-range to desired to the efficiency of long ranges. In sizes is from shoulder-launched weapons. Which is used single-armed to soldiers or tripods fixed the launched the tactical target ranges. It required a squat team to transported fire, handled with air naval and land major forces. The introduction to the contemporary battlefield. It will operate the man-portable ATGMs. Comparing heavy with large missile systems and Advance is the same power and comparing with large missile tripods and similar power and compact handled ability operation systems [9]. And defeat the light and medium tank. Older ages anti-tank infantry missile is such as Anti-tank Rifles, anti-tank rockets (RPG, Bazooka) and magnetic anti-tank mines. Its worked in limited range distance and armour diffusion capability is required closed target approaches. And modern anti-tank missile is identified the years is 2016 and used over the 130 countries.
Types of anti-tank missiles systems:
Its use of GPS satellite signals to accurate or regulate as salvation from an internal navigation system (INS) its application for GNSS/INS systems [10]. The GPS/INS methods are gives is a accurately gather free positions values that used to assigned the values of reset the internal navigation systems blended with it used by the mathematical algorithms, for as a Kalman filters, it is trigonometry angular compass reading of the unit can be contingent from the series of location latitude and longitude or Co-ordinates positions updated from the global position systems [11]. INS/GPS systems benefits are may be calculated by the GPS signal and that the Internal Navigations System can provide the location point of positions and angles updates at fast to analyze the calculation rate of that GPS for heavy impact mount mobilization. And one plus points of GPS is some time lose the signal and the internal navigation systems is continued to complete the task of the intended position and deviation of angle during the period of the lost GPS signal. INS and GPS are 2 types of systems is complementary and worked to accurately the employed mutually. Its commonly used on warships and aircraft and navigation purposes. Its allowed the level positions of velocity and analyzed the calculated rate is quicker than the GPS receiver. Its always allows for accurately calculate the aircraft altitude its rolls, pitch yaw angles. Its usually proposes using the extended Kalman filter (EKF) and Unscented Kalman Filter (UKF) [12]. The UKF is required the estimating of a matrix square root of the state error covariance matrix, used to calculate the overspread of the sigma points for the unscented transform. That lot of ways to determine the calculate the prevailing conditions square root. And have been currently and compared to the GPS/INS systems application. That works is optional to analyzed the Cholesky decomposition linear algebraic methods. GPS and INS are automatically applied for an autonomous navigation area. Its mobilized mount impact vehicles such as warships, tanks, aircraft, bunkers skate slips, roll and tire cornering stiffness estimations.
