Arma 3 - ACE 3 Tutorial - 3.1.1 New Items & Tactical Ladder 

I'm not sure why anyone would dislike your videos, good information, always appreciated.

Hunt IR - If you deploy more than one round. W and S key will cycle through each parachute. And N key is toggle Night Vision Mode. For adjust height of SSWT Tripod. It seem that "Modifier" key (Default LCtrl) is not working lately. You need to change "Modifier" key to other key. I am using "/" right now. It will be work perfectly. This Modifier key still use to rotate Explosive when you are placing as well.

To tilt the ladder to lean up walls, you need to assign and then hold a modifer key while using scroll wheel. Hope that helps.

great video very helpful
