Is there an INI change one can make to keep dead infantry and civilians on the map longer? A minute or two at least? Also, can vehicle husks be made permanent? This is for a campaign mod in which the number of vehicles are limited - they cannot be manufactured, only commandeered.

Part of the campaign I'm making includes a rather graphic depiction of the Kobani massacre. On the same day as the Tunisia beach attack, ISIS infiltrated the city of Kobani, Syria in Kurdish uniforms and murdered over 230 resettled civilians, utilizing car bombs and death squads roving door-to-door under cover of snipers. One mission in this mod attempts to depict this, with the player in charge of the immediate response, trying with the limited forces on hand to eliminate the attackers and minimize civilian casualties.

From the other threads you may have seen around here, this mod contains some unpleasant content. It's an unpleasant subject.
