By realistic I mean reduced HUD, no spotting markers for instance, take time to recon appropriately, work together on VOIP, support squad members with over watch and bounding, med's and so on. My usual approach is to recon, snipe to take out power, alarms, sentries, snipers. Then move in and finish the mission CQC. Just the way I tend to do it, but open to other approaches also. I'm an adult, and in US Mtn time though a few time-zones shouldn't matter. Drop me a line!
