Tactics that kinda worked:
Littlebird and tank combo; 2 tank crewman, pilot, H-AT, (engi would be nice too, but we had 5 guys at the time)
This is simple enough, spot enemy tank from LB before enemy tank has a chance to plink our squad tank. What happened was the other enemy heli showed up, the H-AT was put on the ground and he shot the enemy heli. Nicely done except the whole wrecking on RTB. After the fact something else came to mind, spot enemy tank, drop H-AT in flanking position to hit the enemy tank. Flush the tank out allowing the squad's tank to finish it off if necessary. Pick up H-AT, go to ammo supply, rinse and repeat. Trick is finding a pilot good enough to pull off the LB job. Wheels fell off when the LB crashed on RTB and us in the tank were blind-sided by a T-90 at range.
Stand off H-AT; Officer, 2 Engineer, Designated Marksman, H-AT, Rifleman
After establishing a perimeter around Oil Storage (henceforth OS), or H-AT decided to take a humvee and keep off to the sides. We also sent out a engi to spot tanks inbound to OS. Once spotted the H-At would shift as necessary and keep at a good stand-off range to the sides of the tank, allowing a spotter (the lead engi or otherwise) to call in the results and adjustments needed. We stood off three armor assaults before our sniper left (thus denying us a distant view and good suppression of the dread G3) and our H-AT was plinked. After that the wheels fell off with no H-AT support and the flag fell a few minutes later.
Dual H-AT; 2 H-AT, 2 Riflemen, DM (wish he was medic), (officer would be nice too but I was busy giving ammo and we had 5 guys
Defensive posture only and on a good choke point. This is hard to pull off if only for the fact that its extraordinarily difficult to get 2 H-AT in a single squad. But the precise coordination of 2 H-AT is a force to be reckoned with. Up against our Deployment Point, the two H-AT took out at least 4 tanks and made several fall back relieving pressure on the defensive line. This fell apart after I was taken down by a supporting tank and a MEC manage to grab the kit... Then took down the other H-AT and took his kit... 3 enemy H-AT (2 ours, 1 theirs) with incoming tanks; we had no chance.
What didn't work at all:
CQB and range engagements against G3 Seriously, the three round burst on the M16 needs work. The G3 has us at range, I understand this, its a battlerifle. But the problem remained when the 3burst failed to take down an opponent at point blank range and full auto from the G3 takes down a rifleman and medic in one spray. As it happened, the medic didn't fire because the rifleman was in the direct line of fire, so the return fire was to little to late. I manage to finish the MEC off, but my guys were killed (not CW.) Mid-range fire fights (as in you're able to see the target easily with out a scope) the M16 can hold its own, but range and CQB its at a dis-advantage. Outside of DM, sniper, or armor support, the MEC has USMC standard infantry beaten in almost every aspect and new tactics must be developed to counter the threat the G3 poses.
Engineers in towers; Seriously, get down, lay mines, C4 and get in ambush positions. You have no scope and little range capability, you're no help on a roof or on a oil derrick.
Charging entrenched tanks 2 M1's will lose out to one entrenched T-90, I know, I saw it happen. Spotting and inter-squad communications are a must to take out a stationary tank. Distract the T-90 with M1's and flank with engi's or H-Ats in striking distance with a humvee or LB to take it out. We tried this and it worked 3 out of 5 times. It's rare to have a T-90 with dedicated infantry support, so hitting a blind spot, provided you know them is relativity easy. Charging forward, even with superior numbers, is a sure way for disaster.
Well, I'll add more if I think of them. Right now I'm tired and need to go to bed.
