One potential snag is that most "I" weapons cost SO points. They're really potent in terms of one of the games core issues of prioritizing targets. If they're "free" like regular Mavericks they're going to make many situations a lot easier, and bump your score up. Experiment to be sure, but I think that unless there's an artificial limit or you bump up the point scale you're going to get higher scores with the 114L than you would otherwise.
Am I mixing up Hornet Leader and TAL again? But you se my point.
The US Army has far more SALH Hellfires in stock then MMW versions. MMW is also reliant on the Longbow radar which only equips about 1 in 3 Apache D models - they are very expensive. That alone should make the SO very expensive and not always readily available.
MMW Hellfires are true fire-and-forget weapons (Ever play the PC game Longbow?) which makes them extremely useful for knocking out AAA/SAM units from long range while the AH-64D remains behind defilade cover. Several MMW Hellfires can be launched in rapid succession once the target locations are fed into the MMW seekers.
When using "PopUP" reduce the chance of being detected as the AH-64 only needs to make a quick radar "sweep" and then drop back down again before firing. For SALH launches the AH-64 needs to remain exposed until the Hellfire hits the target.
You certainly were mixing up the two, Andrew. Mavericks don't come for free, and I'd see reason to bump up the SO cost from 1 to 2 points due to the overall expensive quality of the AGM-114L MMW's (Actually, I found out about their abilities from Microprose's Gunship 2000, that game was made back when the AH-64C was considered to be the best Longbow candidate).
