Hey C42, if you're after realism, why don't you use the WGL Wargames pack? Its a total conversions for most of the units in OFP with more realistic values for damage for weapons, vehicle armour etc and includes contributions from lots of addon teams... It's got more realistic features than you can poke a stick at...
Fuel leaks, tailrotor failure, random mechanical failure to name a few and that's just for helos...
Explosions look awesome..! Dust, debris everywhere... Crew served weapons, mortars, MGs etc
Unfortunately, they haven't included the BAS Littlebirds in the pack, so it's just stock BIS helos, but that still obviously includes the UH60 and UH60MG... Besides, they didn't lose any AH6/MH6s in BHD
Latest version is 4.10 with a 500k patch to 4.11... Gotta warn you it's a bit of a beast in size, 100MB or so... But well worth a look if you're after a bit more realism in OFP.
It's the only way I play OFP these days... Just do a Google search for it... You won't regret it...
BTW I'm not affiliated to this addon in any way shape or form, I just think that good work should be praised... OUT
