Nice strat. The Mortar HT is indeed underused.
Have you tried the "old" In before the blitz Airborne strat recently?
What im missing in this strat is sight. Its crucial for 50cals, Scot and Jacksons. Also dont like putting zook on riflemen.
Try this Airborne build in them 2v2's:
Rifle
Rifle
Rifle
Ambulance
Pathfinders
Captain
Drop 50cal
Stuart
Pakhowie or ATGUN (optional, when floating shitloads/situational)
2x Scots
2x Jackson
Put double zooks on RE (get minesweeper first so they are hidden) and Pathfinders. BARS's on Riflemen
When your Stuart is alive when Scots hits the field: swap crews. Keep Pathfinders with zooks near scots to spot and protect. Vet3 pathfinders with zooks dont miss btw
Also dont forget to use supervise with captain to rush the Stuart and the Scots.
initially i was pretty reluctant to put the zooks on the riflemen, and just got 2x on the RE. then i realized if my RE squad wasnt around the luchs can do whatever it wants, so i just put 1 bazooka on everyone. if u combine it with the lmg it makes up for the lost dps. the mortar halftracks are the ones really doing the bulk of the killing anyways. sight can be an issue, but nothing that a bunch of beefy vet 3 rifles running around cant fix.
your build looks interesting tho, ive never considered putting zooks on pathfinders. i dont see a lot of wipe potential compared to the mortar halftracks however.
