Raiders invasion strategies

For those of you that have the following nano units, this works really well.  Front row: empty, crusher, mech trooper, crusher, empty.  Second row:  crusher, samurai, mech trooper, samurai, crusher
 
I generally start with the mech trooper using the arc torch, one on either end. Then I follow with the crushers, using the 21 ton collision, going across the formation. I then clean up with the samurai.  

Using only 7-8 moves,and not losing anyone makes for a happy fight.

I am not using anything else.  So far, have not lost a single unit, even when faced with the double waves.

I use 3 lgnd. Mammoths and the units I want to train. Works every time.

I also use units I'd like to train. 2 portable walls, 2 chunooks and 4 field techs doing a good job. I lost some walls though, but they're ready for rank 6 now. I like Raider events, less armoured units and no airplanes make things a lot easier.

Also found that I mech trooper 2 samurai and 3 crushers work, too.
