If you fly very low and in hot spots switch on afterburner (turets canot follow you and missiles canot follow), you can flyower recon entire island with minimal damage unless scramblers in use.
But that requires flying practice. Never used scout drone due to manta use above.
tomahawk is huge overkill for taking out scramblers and sheld busters. 4 rockets do the trick. And with a bit of practice you can take them with one flyover aswll. And I expected some special applications for tomahawk (maybe carrier turrest or something) for its price.
Never used hammerhead in my campaign and 1 strategy game. Reading comments im surprised that its so weak, in campaign movie it looks bad-ass blast over extended area.
