armed with 7 TL str 6 shots 3 with rending(ish) D6+1 str 7 ignores covers shots this super fast skimmer tank when purchased with holo fields has a 4+ cover save. Add in a guardian squad with conceal lock for 125 points and for 270 you have 10 troops in an AV12 transport with a 2+ cover save provided it moved.
pricey at 270
however compare that to
130 poitns for a scatter laser/cannon wave serpant without holo fields and cheaper 5 man dire avengers squad at 65 its already a min 195 for the serpant and you have to worry about shooting the shield due to only having a 5+ for moving. i think the 85 points and the more bodie inside is good, first 2-3 turns kill anti tanke with mass fire. turn 4 troops get out and on objectives. guardians get in terrain is near enought to scoring wi th the warlock and go to ground. if there are no threats to the wave serpants you conceal them, if not conceal the serpent. then keep firing with that 2+ cover
I am going to try this tactic this week for 3 serpents instead of dire avenger serpents... lots of points, 810 for 3 troops and 3 transports but i think it will be worth it
