It's a variant of the Evil_J short VET Cannon guide using a VET, a MMA and 1 additional GEN for troop transport (fx BHG for maximum speed). If 2 VETs and 1 MMA is used all troops can be transported back after finishing.

Move MMA and VET to X1
Attack C2 directly with VET and get intercepted by C1 and T1 on the way
C1 + T1 + C2 : VET : 1R 1E 242C : 1R max loss
When VET is done with C1 and on the route to T1, attack BC directly with MMA and get intercepted by C3 and C4 on the way
C3 + C4 + BC : MMA : 62R 13S 1E 144K : 62R 13S max loss
Move MMA and VET to X2
C5 : MMA : 7R 1E 212C : 7R max loss
Use MMA as wave 1 and finish with VET
DC : W1 MMA : 1R / W2 VET : 39R 1E 114C 96X : 40R max loss
110R 13S max losses (103R 7S average)
Troops needed : 110R 13S 2E 242C 144K 96X : 607 total troops
EDIT1: This guide is ultrafast. Call for the LS before you make first attack and it can be completed in 37 minutes including troop transport time to the adventure.
EDIT2: If the loot spotter uses a MMA have them hit C5. And change that attack to MMA 1E 219C for zero loss. Saves potentially 7R.
