Strategy
Always keep your tower scattered around the battlefield, especially the back, as the reinforcer has enormous amount of health. It is a flying unit, so don't use infantry against it. The creeps that it summon consume its time, so this is the best time to focus fire on it. Early on, it can provide quite a challenge, but later on, it is pretty much a farmable boss. Highest damage output is required in order to be able to take down this boss. Machine gun works by taking down the creeps it summon, while the laser and rocket tower kills of the reinforcer itself. Infantry can be used against its minion. Many variety of weapon arsenal can be used to make the fight more interesting. An example would include:

Laser only/not allowed

MG only/not allowed

Rocket only/not allowed

Infantry not allowed

Lvl ? Max

Special tower only/not allowed

Feel free to try any of these to provide a greater combat experience.
