## Body

### Mission Overview
Cosmos 836 was launched as part of the Soviet Union's extensive Kosmos satellite program. Satellites in this program often served dual-use functions—scientific research, navigation, reconnaissance, or communications—but were frequently associated with classified military operations.

### Technical Classification
- **Class**: Strela-2M  
  A subclass of low-orbit communication satellites developed for secure point-to-point messaging services, primarily serving Soviet military units.

- **Catalog Numbers**:
  - **COSPAR ID**: 1976-061A
  - **Satellite Catalog Number (SCN)**: 08923

### Launch Details
- **Date**: June 29, 1976
- **Time**: 08:12 UTC
- **Launch Site**: Plesetsk Cosmodrome, **Site 132**
- **Launch Vehicle**: **Kosmos-3M**, a two-stage liquid-fueled rocket commonly used for launching small satellites into low Earth orbit

### Operational Context
The Strela-2M system was designed to relay encrypted messages over long distances without reliance on ground-based infrastructure. These satellites operated in low Earth orbit and formed part of a larger constellation aimed at enhancing communication resilience for Soviet forces.

### Legacy and Documentation
While detailed operational information remains limited due to the classified nature of such missions, Cosmos 836 is documented in several public aerospace databases and has partial coverage in Serbian, Macedonian, and Croatian Wikipedia editions.
