Which version of the AGM-65 comes with a 300lb heavy blast and employs infrared guidance?

The version of the AGM-65 that comes with a 300-pound heavy blast warhead and utilizes infrared guidance is indeed the G variant. This version is specifically designed for use against armored vehicles and features advanced imaging infrared guidance for increased accuracy. The 300-pound warhead is effective against a variety of targets due to its heavy blast capability, making it suitable for close air support missions.

In contrast, other variants of the AGM-65 have different characteristics and guidance systems. For instance, the D variant uses a laser guidance system and is often employed for precision strikes on point targets, while the H variant is equipped for high-altitude engagements with a different warhead and guidance mechanism. The K variant, on the other hand, is usually focused on additional capabilities that differentiate it from the others, often with a focus on specific target sets or platforms. Therefore, the G variant's combination of the 300-pound heavy blast and infrared guidance distinctly identifies it within the AGM-65 lineup.
