I had originally opted for iron bombs for anti-runway as the AI sometimes miss with the Durandals because they release them from too high an altitude. But after using them for a while, I am finding they appear to do no worse than with iron bombs. So, might as well let them use the dedicated anti-runway weapon.
DCS AI cannot yet use LGBs.
A2G loadouts for anti-unit have been switched to CBU-97s, which appear
to be the most effective weapon type.
A2G loadouts against static targets (OCA/aircraft, OCA/runway, strike)
have been change to Mk82s and Mk84s.
