## Abstract

A retractable light turret mounted in a platform, a firing device that can be deployed through an opening in a protective cowling for ensuring the closing of the opening, and elevation and azimuth aiming devices for the firing device, wherein the protective cowling has, on its external face, a close-in defense device, and at least one observation device coupled with a display device arranged inside the platform.

## Claims

### Claim 1

A retractable light turret mounted on a platform, the retractable light turret comprising:
a firing means capable of deployment through an opening in the platform;
a protective cowling ensuring closing of the opening;
elevation aiming means for the firing means; and,
azimuth aiming means for the firing means;
wherein said protective cowling has an external surface comprising:
close-in defense means;
at least one observation means coupled with display means, the display means arranged inside said platform.

### Claim 2 (depends on 1)

A retractable light turret according to claim 1, wherein said close-in defense means comprise at least one means for dispersing a lachrymatory agent.

### Claim 3 (depends on 2)

A retractable light turret according to claim 2, wherein said close-in defense means comprise at least one means for dispersing a fire-extinguishing agent.

### Claim 4 (depends on 2)

A retractable light turret according to claim 2, wherein said means for dispersing said lachrymatory agent is linked to at least one pressurized storage container inside said platform.

### Claim 5 (depends on 3)

A retractable light turret according to claim 3, wherein said means for dispersing said fire-extinguishing agent is linked to at least one pressurized storage container inside said platform.

### Claim 6 (depends on 1)

A retractable light turret according to claim 1, wherein said protective cowling bears at least one target designation means on the external face of the cowling.

### Claim 7 (depends on 1)

A retractable light turret according to claim 1, wherein said protective cowling is integral with said firing means and can pivot in azimuth with said firing means both in its open position and in its closed position, thereby enabling said close-in defense means and said observation means to be oriented.

### Claim 8 (depends on 7)

A retractable light turret according to claim 7, wherein said firing means is moveable from a retracted position into a deployed position by means of at least one pair of arms forming a deformable parallelogram.

### Claim 9 (depends on 8)

A retractable light turret according to claim 8, wherein the length of one of said arms of said deformable parallelogram can be modified by an actuator thereby enabling aiming in elevation of said firing means in said deployed position.

### Claim 10 (depends on 1)

A retractable light turret according to claim 1, wherein said firing means comprise a unit having at least two boreholes each for accommodating a projectile.

### Claim 11 (depends on 10)

A retractable light turret according to claim 10, wherein said two boreholes are of different calibers.
