I recently modded my Arma 3 with the latest version of the aggregated mods by SimHQ.com. By the way, SimHQ is one of the best places to play Arma 3 online. They offer a semi-casual atmosphere that will serve very well to mature players both casual and pro.
So, as seen above I'm fighting like it is 1991 :) and getting my hands dirty with the new suppressive fire command. I have a US fireteam that includes a light (or medium?) machine gun.
|This enemy MG is located at an entrance of a campground, with some defile protecting him from our guns.|
|Suppressive fire on that entrance! They shoot nice and long enough for me to watch and move towards the enemy.|
|The enemy goes prone, under fire. This is not new. The new thing is my fireteam shooting at the entrance (note the impact of rounds) in a direction where they don't see a target.|
|And take a look at this: you can order suppressive fire using the map. Just remember that your soldiers can't shoot what they can't see, so check if they can see their suppressive fire aim point.|
|A new round of suppression allows me to get really close for the final assault. Not the dust lifted by the rounds impacting nearby the entrance.|
|An it goes downhill from here. The enemy bot gets very distracted by the suppressive fire (he keeps aiming at my unseen men). He throws a grenade and that allows me to see and shoot him in the head. Done!|
Make sure to check out this new feature. It works best when you are a squad leader. Just make sure that you don't walk onto your men's line of fire. Or call a suppressive fire mission too close to you ... I once got blown by a tank under my command while doing that.
