Which IR AAM rule represents Rear Aspect Only, No IRCCM, LOBL?

Which IR AAM rule represents Rear Aspect Only, No IRCCM, LOBL?

• A. IR-4
• B. IR-1
• C. IR-2
• D. IR-3

Answer: (B)

The key idea here is how IR AAM rules define how and when a missile can be engaged based on three constraints: the aspect of the target (where the target is relative to the shooter), whether infrared counter-countermeasures (IRCCM) are allowed, and whether you must lock the target before launch. The combination described—Rear Aspect Only, No IRCCM, and Lock-On Before Launch—matches a specific rule that restricts engagements to targets behind you, prohibits relying on IRCCM features, and requires you to have a lock before firing. This exact set of constraints is what defines IR-1. The other rules describe different mixes of these factors (for example, broader engagement angles, or allowing LOAL instead of LOBL, or permitting IRCCM), so they don’t fit this particular combination.
