Edit: As of r8116 & GameDir r2306, merc profile 71 (formerly the unused RPC71) is now used for the combat jeep. In Vehicles.xml, combat jeeps now get armor similar to kevlar vest as tank has spectra. Note that this is somewhat misleading, as the previously mentioned ammo modifiers are still evaluated. LAWs, however, seem to do a bit more damage - I've tested this several times. Most of the times a single LAW kills a combat jeep, but I've also seen it only deal 72 damage. Seems fair to me - almost but not a guaranteed kill.
