Hi I'm frisko12, and I'll be giving you the places to put certian units and guns in the game,Endless War Defense. First of all always put your AT troopers on the front line,as it will be doing the most against tanks. Second of all put all your guns in the back becuse it will protect them.Third of all the unit put farthest back should be snipers since they have the longest range. Hope this helps!
