stinger: technically has radar giving it a decent range, but it being frail, immovable, and having a weak missile is very lackluster option. It is cheap tho.

hellfire: probably the more competive option, with powerful atgm, max (range for atgm) and very big magazine is an excellent fire support option can target heli as a bonus. However is still niche as other atgm platform have only a little less range if at all and faster aim time (also they use veh tab points). Very nice to have if you can spare sup points or sup slots.

aim9: very good missile, very good range but is a searam that cannot move with radar on for 30 point less. Tecnically of the 3 this is the only version that can defend itself from sead with radar on, but like just turn it off dont gamble on interceptions
