-- Simple Class for a more intelligent Air Defense System
--
-- #MANTIS
-- Moose derived Modular, Automatic and Network capable Targeting and Interception System.
-- Controls a network of SAM sites. Use detection to switch on the AA site closest to the enemy.
-- Leverage evasiveness from @{Functional.Sead#SEAD}.
-- Leverage attack range setup added by DCS in 11/20.
--
-- Set up your SAM sites in the mission editor. Name the groups with common prefix like "Red SAM".
-- Set up your EWR system in the mission editor. Name the groups with common prefix like "Red EWR". Can be e.g. AWACS or a combination of AWACS and Search Radars like e.g. EWR 1L13 etc.
-- [optional] Set up your HQ. Can be any group, e.g. a command vehicle.
--
-- # 1. Basic tactical considerations when setting up your SAM sites
--
-- ## 1.1 Radar systems and AWACS
--
-- Typically, your setup should consist of EWR (early warning) radars to detect and track targets, accompanied by AWACS if your scenario forsees that. Ensure that your EWR radars have a good coverage of the area you want to track.
-- **Location** is of highest importantance here. Whilst AWACS in DCS has almost the "all seeing eye", EWR don't have that. Choose your location wisely, against a mountain backdrop or inside a valley even the best EWR system
-- doesn't work well. Prefer higher-up locations with a good view; use F7 in-game to check where you actually placed your EWR and have a look around. Apart from the obvious choice, do also consider other radar units
-- for this role, most have "SR" (search radar) or "STR" (search and track radar) in their names, use the encyclopedia to see what they actually do.
--
-- ## 1.2 SAM sites
--
-- Typically your SAM should cover all attack ranges. The closer the enemy gets, the more systems you will need to deploy to defend your location. Use a combination of long-range systems like the SA-10/11, midrange like SA-6 and short-range like
-- SA-2 for defense (Patriot, Hawk, Gepard, Blindfire for the blue side). For close-up defense and defense against HARMs or low-flying aircraft, helicopters it is also advisable to deploy SA-15 TOR systems, Shilka, Strela and Tunguska units, as well as manpads (Think Gepard, Avenger, Chaparral,
-- Linebacker, Roland systems for the blue side). If possible, overlap ranges for mutual coverage.
--
-- ## 1.3 Typical problems
--
-- Often times, people complain because the detection cannot "see" oncoming targets and/or Mantis switches on too late. Three typial problems here are
--
-- * bad placement of radar units,
-- * overestimation how far units can "see" and
-- * not taking into account that a SAM site will take (e.g for a SA-6) 30-40 seconds between switching to RED, acquiring the target and firing.
--
-- An attacker doing 350knots will cover ca 180meters/second or thus more than 6km until the SA-6 fires. Use triggers zones and the ruler in the missione editor to understand distances and zones. Take into account that the ranges given by the circles
-- in the mission editor are absolute maximum ranges; in-game this is rather 50-75% of that depending on the system. Fiddle with placement and options to see what works best for your scenario, and remember **everything in here is in meters**.
--
-- # 2. Start up your MANTIS with a basic setting
--
-- `myredmantis = MANTIS:New("myredmantis","Red SAM","Red EWR",nil,"red",false)`
-- `myredmantis:Start()`
--
-- [optional] Use
--
-- * `MANTIS:SetEWRGrouping(radius)`
-- * `MANTIS:SetEWRRange(radius)`
-- * `MANTIS:SetSAMRadius(radius)`
-- * `MANTIS:SetDetectInterval(interval)`
-- * `MANTIS:SetAutoRelocate(hq, ewr)`
--
-- before starting #MANTIS to fine-tune your setup.
--
-- If you want to use a separate AWACS unit (default detection range: 250km) to support your EWR system, use e.g. the following setup:
--
-- `mybluemantis = MANTIS:New("bluemantis","Blue SAM","Blue EWR",nil,"blue",false,"Blue Awacs")`
-- `mybluemantis:Start()`
--
-- # 3. Default settings
--
-- By default, the following settings are active:
--
-- * SAM_Templates_Prefix = "Red SAM" - SAM site group names in the mission editor begin with "Red SAM"
-- * EWR_Templates_Prefix = "Red EWR" - EWR group names in the mission editor begin with "Red EWR" - can also be combined with an AWACS unit
-- * checkradius = 25000 (meters) - SAMs will engage enemy flights, if they are within a 25km around each SAM site - `MANTIS:SetSAMRadius(radius)`
-- * grouping = 5000 (meters) - Detection (EWR) will group enemy flights to areas of 5km for tracking - `MANTIS:SetEWRGrouping(radius)`
-- * acceptrange = 80000 (meters) - Detection (EWR) will on consider flights inside a 80km radius - `MANTIS:SetEWRRange(radius)`
-- * detectinterval = 30 (seconds) - MANTIS will decide every 30 seconds which SAM to activate - `MANTIS:SetDetectInterval(interval)`
-- * engagerange = 85 (percent) - SAMs will only fire if flights are inside of a 85% radius of their max firerange - `MANTIS:SetSAMRange(range)`
-- * dynamic = false - Group filtering is set to once, i.e. newly added groups will not be part of the setup by default - `MANTIS:New(name,samprefix,ewrprefix,hq,coaltion,dynamic)`
-- * autorelocate = false - HQ and (mobile) EWR system will not relocate in random intervals between 30mins and 1 hour - `MANTIS:SetAutoRelocate(hq, ewr)`
-- * debug = false - Debugging reports on screen are set to off - `MANTIS:Debug(onoff)`
--
-- # 4. Advanced Mode
--
-- Advanced mode will *decrease* reactivity of MANTIS, if HQ and/or EWR network dies. Awacs is counted as one EWR unit. It will set SAMs to RED state if both are dead. Requires usage of an **HQ** object and the **dynamic** option.
--
-- E.g. `mymantis:SetAdvancedMode( true, 90 )`
--
-- Use this option if you want to make use of or allow advanced SEAD tactics.
--
-- # 5. Integrate SHORAD
--
-- You can also choose to integrate Mantis with @{Functional.Shorad#SHORAD} for protection against HARMs and AGMs. When SHORAD detects a missile fired at one of MANTIS' SAM sites, it will activate SHORAD systems in
-- the given defense checkradius around that SAM site. Create a SHORAD object first, then integrate with MANTIS like so:
--
-- `local SamSet = SET_GROUP:New():FilterPrefixes("Blue SAM"):FilterCoalitions("blue"):FilterStart()`
-- `myshorad = SHORAD:New("BlueShorad", "Blue SHORAD", SamSet, 22000, 600, "blue")`
-- `-- now set up MANTIS`
-- `mymantis = MANTIS:New("BlueMantis","Blue SAM","Blue EWR",nil,"blue",false,"Blue Awacs")`
-- `mymantis:AddShorad(myshorad,720)`
-- `mymantis:Start()`
--
-- and (optionally) remove the link later on with
--
-- `mymantis:RemoveShorad()`
--
-- @field #MANTIS
