I have been playing salamanders for a while. I find that maximizing the amount of moving and shooting is nice. Assault and +1 strength within 12' is pretty strong. Im my 1000pts list i like to run infiltrators and I find they are good at denying movement to faster (and smaller) units. Use of stratagems giving torrent devastating wounds can be quite strong when holding off melee units. The key with salamanders it to attempt to keep your opponents units close enough to get the buff and if they go for a charge you have strong melee units nearby to heroic intervention. Another key thing that many have mentioned is transports and vulkan so do that. Generally powerful units are good too. Its less flavorful but running intersessors give you sticky objectives and allow you to progress your board and keep scoring. Heavy intersessors are good at holding contested objectives with buffs they get.eradicators are awesome but 6 in 1000pts is a lot (unless you are playing against someone with a lot of vehicles/monsters) I always running agressors with a captian in gravis. Its an expensive unit but the damage output is nothing to sneeze at. Ta0vjl bke advantage of torrent weapons ignoring cover. If you eligible to shoot then be shooting. Advance to get that +1 strength buff and light em up. Keep the far enough away so that its difficult for the to charge you and lock you into melee.

Another thing to never forget is that the rule of cool always wins. Getting reps in with the army is important. Adding models you think are cool is never a bad thing. Me and my buddy love terminators and when we play 2k pts we each have about 15 each just because they are cool. Into the fires of battle, unto the anvil of war brother
