3x phoenix = 6A, 6W, AR 22 - 99 points
2x attilas = 6A, 6W, AR 22 - 86 points (weak AC? - 10x2, AV-2, with RC 11?)
more or less,
its a little more than 2 attilas, see my calculation on AC, W
the autocannon is not bad, or an AR, but it is no HMG
the mashinegun gets boni closer, the AC just negative (after PB). also, it is not DAM14
head problem with phoenix is move - when you must move with army (not be sitionary, but in maneuver combat), his movement is too small (6 inch/round).....
well.. if together with 2 or 3 vehicles they are very good meatshilds
of course, they donīt get in range, but they are good W/P/AR value.
if you advance in cover you will be max 2-3 rounds in the open.. 2 A is few, but not to few. no shooting with this tactic likely, though.
IF you get charged, they are there then and mow down any CC speadfreaks..
