Another enemy idea i've come up are strike teams like a swat squad. The main intention is to have a rapid, focused, easily killable but very damaging team of enemies that strike instantly and can cripple your monster easily if not under check.
- When the van approaches the monster enough, it deploys its team of six police men.
- After that the police men engage the monster with their weapons.
- When attacking, some of the police men can throw grenades against the monster, causing heavy damage.
This in conjunction with drop-in military personnel will result in a complicated task management to keep the small ones on check.
Like the police car, the police men will flee to the swat van after depleting their ammo on the monster.
