Battle of Chiclayo, Peru.
As the aircraft approach Chiclayo, they are forced to delay for longer than desired due to a steady stream of evacuation flights, with planes backed up landing and taking off trying to rescue people. The city does look fairly dramatic, with only a few buildings on the beach and starkly irrigated fields in the desert, with most of the city a good ways inland. You can identify some of the militia from here, with a small handful of trucks and maybe fifty people lined up along the beach.
Eventually, you do get down, after applying pressure that would have caused an internation incident in a less dire situation. You aren't able to deploy until well after the kaiju comes out of the water, and engages the militia.
This kaiju is an enormous wolf, although it's blue and naked, with the standard kaiju thick blue skin. It doesn't look right, as dogs should have fur. On it's back is a missile launcher, vaguely similar to the lobster one from Australia. In addition to that, it can launch bright neon-colored lasers from it's eyes, and they just seem to delete stuff. Unprecedented, you see a third weapon being used; the Kaiju opens its mouth and there is a huge splash of what looks to be bullet effects hitting nearby sand and buildings. After action cameras will reveal this weapon to be a swarm of high speed metal shards hitting an area. A shardstorm.
Anyway, the militia can't handle that much damage and are mostly wiped from the board in a shower of metal bullets, explosions, and laser beams.
Eventually, the troops are moving, and the kaiju is moving inland towards the city. The range is somewhat close, causing the jets to open the distance to try for a safe chance to get their missiles away, while the tanks, the artillery, and most of the infantry charge the enemy. Waspra happily buzzes away towards the giant monster, looking ready to engage despite the disparity in sizes.
Before they can shoot, however, there is a surprise. This kaiju isn't attacking the city first, waiting to be struck. This kaiju is attacking the defending military units first.
With that, the tank units are attacked. A missile streaks out towards the Coke Knight's modern tank. The tank, already encased in a rippling force-field, is further surrounded by a giant explosion of flame from a direct hit. The shield almost holds, but is collapsed as the explosion drags on, and although you cannot see everything, the tank is knocked 90 degrees out of line and the turret and treads are fused stuck from the intense heat. The tank was knocked out, but should be recoverable.
The laser eyes strike at a second tank. This time, it's hitting Happytime Atrocities' brand new Challenger II. In the words of Dwarf Fortress, "It is pierced through entirely." There is a jet of explosives from the active armour, but in the end the eyes cut completely through the tank, from one end to the other. The hole is clean, however, and it also should be recoverable.
The shardstorm attack also hits the tanks, as if they're deliberately being prioritized. This one aims at happytime's normal modern tank, hitting both T-55s at the end of it. Two are knocked out with the hail of large-caliber bullets, Happytime's modern tank just barely, and Emerald Robin's T-55 more significantly, and the Coke Knights T-55 lives.
That's.. a significant advantage after the opening strike. The k-com units were outranged and the kaiju, targetting military forces first, was able to use the relatively slow deployment to get first strike on the tank force.
The jets are still flying, and they will enter range in two more turns, lining up for an attack that minimizes their chances of getting hit before unloading. Two infantry units are closing, as is Waspra, and the assault fish, and the artillery piece with the surviving T-55. The tank and the artillery return fire, doing little damage as the shots bounce off the thick blue skin.
On the next round, the kaiju attacks the CK force-fielded T-55 with all three weapons. It does survive some of the oncoming fire, but cannot handle the full alpha strike and is blown to smithereens.
Waspra, the sonic-armed Plymouth Barracuda, and the USSCCI artillery shoot back. The artillery bounces, the barracuda closes to close range and the sonic weapon is resisted, but only with great effort from the kaiju, skin rippling for several long moments after the blast has ended.
And Waspra, well, waspra manages to sting the giant beast, drawing first blood and dealing at least some damage to the creature.
In retaliation the kaiju hits it with a pair of laser eyes and a shardstorm. The eyes punch through the upper body, killing the creature, and the shardstorm mostly shreds the mess. The missile launcher goes for the assault car, which manages to get some cover and only takes a glancing blow. It's enough to knock out the lightly-armoured vehicle anyway, but it should be fixable once more.
At that, the Jets have finally re-entered range, and the wing of three attack the kaiju from multiple directions. It's hit heavily, including one missile that catches it off-balance and physically knocks the massive creature down. When it gets back up, you can see the skin rippling effect, so common with recent kaiju, has been disabled, and the wounds aren't healing.
..still, it is so big, larger than the other kaiju so far, that the wounds seem relatively small.
The kaiju's return fire drops one of the jets with a missile, and begins working on the infantry, causing casulties and damage but not enough to wipe them out. They fight back furiously, scoring another hit from the USSCCI rockets. This is followed up by a blow from one of the jets.
Still, it's not enough. The kaiju drops a second jet with a shardstorm, and continues piling on the damage, largely ending the battle when the following jet salvo fails to penetrate the tough skin, and the damaged regeneration kicking in once more.
The rest is cleanup. The final jet from the USSCCI retreats after it runs out of ammo, barely dodging a blast from laser eyes, and the Emerald Robin's infantry unit which had orders not to engage, are the only survivors. The kaiju proceeds to the city and begins to smash. Stomping with its feet, slamming into buildings, and firing away with its weapons.
Although much of the population was warned and was able to evacuate, a minimum of tens of thousands are dead, in the space of a few hours, because of your failure to stop it. The Emerald Robin infantry can basically force their way through the fleeing crowds, so they're able to survive, but there is little point to personal heroics when the kaiju is still smashing away.
At least there is some reassurance. To date, every kaiju that has won a battle simply retreats to the sea in the evening, instead of, perhaps attacking more cities. Its survivors mostly hope that this pattern will hold true.
Several hours later, as the sun is setting, the kaiju simply returns to the sea, victorious.
