tips on hitting npcs levels 1 - 5 without lossing troops

There are ways of hitting npcs without lossing any troops they are

level 1 npc, use 50 ballisters and 43 transports with the min requirement of archery level 6 and transports(logictics) at 0
level 2 npc, use 100 ball and 71 transports with the same min requirements to level 1
level 3 npc, use 150 ball and 240 transports and same min requirements as level 1 and 2
level 4 npc, use 350 ball and 452 transports with min requirements of level 7 archery and 0 for transports
level 5 npc, use 1000 ball and 798 transports with min requirements of level 8 archery and 0 for transports

Using these will will result in fewer loses in attacking npcs for resources. Transports become lower with the higher logistic reserched
eg. level a level 5 npc with a archer of level 9 and logistics of level 6 would require a 500 ball and 500 transport sent with no losses.
these have worked for me and will work time and time again with no losses

plz post any that you find to help others out
