Yes. The artillery barrages look nice but only take out the single target designated when the strike is called. On the other hand, an A-10 Airstrike is quite effective at taking out multiple armored vehicles...but it is wise to first clear out any SAM threat or the Warthog will go down.
Yeah airstrikes did cross my mind when replying but I thought that after I'd explained about arty, it had got complicated enough! Good advice though.
Another hint you may or may not be familiar with. In LB2, anyway. Not sure if this applies to LBG...calling for an Airstrike with an friendly helo targeted results in an F-16 essentially flying escort. I usually do this in Escort missions to help protect the Chinooks or Blackhawks against enemy helos, but, again the F-16 is vulnerable to SAMS along the path.
Wow, I never knew that! Excellent hint!
