Tank battle server

The Theory

There are two teams on opposite sides, colours can be changed but blue and red are standard. The red team is the defending team and have a minute to set into position, this can be done by giving the blue a slowness potion (New command blocks so slowness 100 or whatever), after the minute the potion will wear off and the game will begin.

There will be many maps with different scenery and weather (Desert, forest and snow).
There will be tanks build into the map in locations and the aim it to blow up the red teams tanks.

Players will not be allowed to place or break blocks bar the tnt for the blue team.
-----------------------------------------------------------------------------------------------------------------------
Blue will spawn with and have when the respawn:
1 tnt
Blue leather armour
an iron sword
bow with infinity
food
splash potion of damage for grenades.
-----------------------------------------------------------------------------
Red will spawn with and have when respawn:
Red leather armour
Iron sword
Bow with infinity
Food
Splash potion of damage
-----------------------------------------------------------------------------------------------------------------------
When a player is killed there food and splash potions will be dropped all other items should not be able to be picked up.

There will be a number of tanks on a map and as i said the aim is for blue to eliminate them, they can do this by putting the tnt on a redstone block, located in the middle of the tank (Depending on size there may be more than one location)
once the tnt is placed fireworks will go off like an explosion and the tnt will do the damage. A score board will need to be implemented to keep track of the remaining tanks. Blue wins by destroying all the tanks and Red wins if they don't destroy them within a time limit (Varies on map size and team size). Once a game is over the map will be reset and players will be moved to a new map (map resolvent system).
This is the basic principle however there are many possibilities e.g:
Anti-tank guns
planes / bombers
tnt cannons
mines
sticky bombs
bazooka
replace bows with guns
