Description
The Chaparral is an SPAA used by the United States between 1969 and the early 2000s. It was a cheap way to adapt an already existing and trusted platform like the M113 to provide close- to medium-range air defence. For this, the AIM-9 Sidewinder missile was used, with different seekers and engines being installed over the years in order to provide better target acquisition, range, and reliability. The Chaparral also saw medium success in international markets, serving with Ecuador, Chile, Egypt, Morocco, Taiwan, and Israel. The only confirmed kill was a MiG-17 shot down by Israel over the Golan Heights.
Introduced in Update "Sons of Attila", the Chaparral comes with the benefit of using IR-guided missiles, though lacking IRRCM can be flared away with countermeasures and a couple of manoeuvres, but it makes it so that no radar is required, which means no ground clutter or lock warning for the pilots. Many jets at the BR lack countermeasures, so its most major opponents are modern ground attack aircraft like the A-10 and Su-25 that have armament capable of outranging the Chaparral and also have countermeasures. The other problem the Chaparral suffers is the lack of a gun; since it has no cannon or HMG, it is not able to shoot down helicopters or jets that are too close to hit as there is a slight delay after launch before the missile starts tracking.

Survivability and armour
Describe armour protection. Note the most well protected and key weak areas. Appreciate the layout of modules as well as the number and location of crew members. Is the level of armour protection sufficient, is the placement of modules helpful for survival in combat? If necessary use a visual template to indicate the most secure and weak zones of the armour.

Usage in battles
The first and most noticeable jump from the M247 to the Chaparral is the lack of radar. This lack of radar can take some time getting used to but is not a downside; the lack of a radar (and therefore having nothing to trigger a Radar Warning Receiver or RWR) renders you invisible to most detection barring direct line-of-sight and late generation missile approach warning systems (MAW). Even though searching for targets is more difficult, it also makes you more difficult to be found. Due to the IR locking, the target will not detect the lock and, thanks to the smokeless missile motor (available once the MIM-72E is unlocked) may not notice the launch, meaning that there is only a split second window after firing where you can be detected. However, it is generally recommended to relocate after your launch as other aircraft may have noticed. Typically missiles should be fired in pairs, waiting approximately 2-3 seconds between launches. With a full ammo load this typically results in 4-6 semi-guaranteed shootdowns. The lack of IRCCM and being a early generation IR guidance also means the missiles are capable of being locked on to the sun, though if need be this can be used to "dump" your last missile to start a reload early.
There are several ways to avoid missing;
- Avoid firing the missile before the target has fired flares, chances are they've been locked by another SPAA and are trying to avoid them. This leaves you the perfect window to fire and cripple them.
- Avoid firing when the target has lots of energy, the less energy the target has means a higher chance you will hit them. Try firing after they've finished an evasive maneuver.
- In rear aspect, the missiles generally ignore flares which means that you will be able to lock and fire before they have chance to avoid it. Try to pre-emptively aim in rear aspect so that you can destroy the aircraft after they've passed overhead.
- Don't fire at distant targets travelling transversally, the missiles tend to overcorrect and have a decent chance to miss their target.
- Remember that the missile is attempting to intercept the target, and therefore will be aiming for where the target will be, and not where it is.
As this is the first missile-centric SPAA, actively engaging targets takes a lot less time and effort as the missiles themselves do much of the work for you. Four missiles give plenty of chance to destroy a target in the event that the missile is evaded.
Pros and cons
Pros:
- IRST tracking (undetected by RWR)
- Infrared missile guidance provides more stealthy attacks compared to missiles that rely on radar (fire and forget, no painting to alert enemy RWR)
- Harder-hitting and slightly more manoeuvrable missiles compared to its successor the LAV-AD
- Can perform scout functions for extra team assistance
- Thermal imaging to assist with target acquisition
- Missiles lack of IRRCM can be used to lock onto intercept some ATGMs (Results may vary, no payout provided for successful intercepts)
Cons:
- Missile armament lacks IRCCM
- Absolutely no defensive armament, strictly anti-air
- No armour
- Lacks search radar (must rely on visual and sound to find enemies)
History
The Chaparral was an anti-aircraft system developed by the United States during the 1960s to offer short-range air defence capabilities to soldiers and armoured units. The Chaparral employs variants of the AIM-9 Sidewinder missile instead of traditional radar-guided missiles and it was meant to be used together with the M163 VADS.
The Chaparral's predecessor was the Mauler, developed during the Advanced Air Defence Program and using the MIM-46 Mauler missile. It was equipped with a total of 9 missiles and no gun, the system was mounted in the M113 chassis and also had 2 radars available. The Mauler was abandoned in 1963 after many problems were discovered with the system, but many of its characteristics were inherited by the Chaparral.
For example, the attempts to modify the M113 to add an SPAA system to it continued in the following years, with the MIM-72 Chaparral going into service in 1969. The Chaparral was a cheap and quick solution to the lack of short-medium range air defence options in the army. This was result of the Provisional Advanced Air Defence program, that evaluated the AIM-9 missile as an option for ground-based AA platforms. However issues started to appear when it was evident that the AIM-9 would not have enough time to react if the enemy aircraft was too close, thus, an M113 was equipped with an M61 Vulcan 20 mm cannon and a radar was to be used in complement to the Chaparral. A separated radar set was developed to be used with both the Chaparral and Vulcan system, however this system is transported by a separate unarmed vehicle and was not suited for frontline combat.
Different versions of the Chaparral appeared in later years, especially during the 1970s and '80s. The Chaparral was seen as a cheap alternative for air defence platforms and was exported to several nations. Most upgrades consisted in improvements to the fire control system and armament, with better missiles adapted to be used in the Chaparral. All-aspect seekers were installed in 1974, and even a naval version was exported to Taiwan after not being of interest to the army.
The MIM-72D was an export variant with improved warhead, the MIM-72E was used during the 1970s and '80s and included a smokeless engine. The most modern variant was the MIM-72G, that used the seeker of the FIM-92 Stinger missile, with deliveries of this new version starting in 1982, and all missiles being modified with the new seeker. After 1981, the system started to be phased out from the regular army, but it was still used during the Gulf War. In the end, all systems were handed over to the US national guard.
