Nilikuwa na some older guys who think of themselves as being knowledgeable matters military, but the things they were talking about, ni zile situation hata hauongei, ni kuamka na kuenda kutafuta kitu ya kupapasa koo.
Let me make some distinctions msichochwe hapa ktalk alafu mkienda baraza mtaani hamjui vitu mnasema.
1. A Tank.
The most distinguishing feature of a tank is a gun turret, which is a location from which weapons can be fired that affords protection, visibility, and some cone of fire. A modern gun turret is generally a weapon mount that houses the crew, or mechanism of a projectile firing weapon, and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Hence why you see tank guns swiveling side to side and the gun pointed up or down. They are usually heavily armoured to protect the crew, and are fast. Like real fast. Some can do 110 kph and still fire on target.
2. Self Propelled Gun.
These are the ones people generally call tanks because they look like tanks, but are no where near them in terms of speed, mobility, and armour protection.
They are literally guns on wheels/tracks. They are used to give indirect fire support to infantry.
Before I go further, their are marked differences between a ‘gun’ (characterized by a longer barrel, larger propelling charges, smaller shells, higher velocities, and flatter trajectories), ‘howitzer’ (relatively short barrel and the use of comparatively small propellant charges to propel projectiles over relatively high trajectories, with a steep angle of descent), ‘mortar’ (even shorter barrel which was meant to fire at even higher angles of ascent and descent).
These (the tracked mostly) can raise guns up and down, but rare to find those that can swivel side to side (no turret). Za KDF zimewekwa kwa lorry.
In these category also there are self propelled mortars, air defence guns
There is this other one called Multiple Launch Rocket System

3. Armoured Cars
That is what they literally are. Car size military, er… car… SUV with light armour and some form of weaponry on them, like a mortar or a small gun. These are utilised mainly by scouts and recon troops who need to move fast, defend themselves if under fire, or lay down fire for a small team to retreat. Niko sure mumeona hizi za KDF kwa wingi. They were upgraded by Israelis in 2007

4. Armoured Personnel Carriers
These are self explanatory. Some have weapon mounts, but for machine guns and autocannons. They can be wheeled or tracked. They have some armour and are used to carry infantry into battle and give them limited fire support. They are also good as ambulances.

With the evolution of war, machines also evolve and this one grew into Infantry Fighting Vehicles, and Infantry Mobility Vehicles/Mine Resistant Ambush Protected vehicles.
5. Infantry Fighting Vehicles
Now these carry troops into battle, and give them direct fire support. Others are so good they are known as tank killers. You have troop carrying capacity plus a tank gun/autocannon/missiles on top and they move fast. South Africans pioneered these things with the Ratel, during the border war with Angola in the 80’s. Most countries discovered them much much later…

These things are so good, Americans are reorganising their ground fighting units based around these things (Stryker Brigade Combat Teams). When paired with tanks, blitzkriegs take place as witnessed in Iraq (the second time they went in).
And finally…
6. Infantry Mobility Vehicles/Mine Resistant Ambush Protected vehicles.
Another South African first (actually Rhodesia. SA just made them better) with the Casspir (what the Ugandans have) and Buffel (this one is ugly, wah!!). Characterised by V shaped hulls to defelct mine explosion, high ground clearance, wheeled for ease of mobility and armoured to protect occupants.
