Hi, the LDK are getting ridiculously hard to kill. My MO has given up the NATO ammo in favour of the AK AP ammo. But it is a waste of time trying to use any form of explosion except possibly RG7 ammo etc. An HK sub machine gun will kill, so will the AK94 Gulag Mo favours but at one point MO fired AP directly at an LDK soldier's head with no affect until a switch to the Barratt did the job. Some LDK have face armour, but others less than Bandits and yet they too are impervious. Please consider upgrading the grenades of both kinds launched and thrown, and armour-piercing rounds from 7.62x54 B30 to the HK and NATO ones, to have sufficient penetration. Thanks and regards, TrueB.
