Okay I got some more tricks! 
Utilize Flares and Fireworks to lure those pesky deployed Ticks, if they have been out long enough they will destroy themselves.
Thermal Vision highlights machine Armor and Components. Dark blue or black for Components, yellow or orange for armor. This helps if your toon is designed for dealing damage to those categories specifically.
Tall propane tanks (mainly in warehouses) have the largest explosive radius (that I know) and will set off all electric panels near the explosion. Do not be near them during a mortar attack, use them to destroy large groups or powerful opponents. There is a specific warehouse in the South Region that has multiple military runners and hunters inside, shoot an electrical box and watch the sparks fly!
If you think you are going into a fight that may be over your head, place a way point to a fall back area, or use ammo boxes / med boxes as indication.
If you are in need of supplies, re-scavenge old bunkers you have explored. Most abundant in resources.
Deployable propane tanks are most found in warehouses.
That is all I can think of for now!
