Job Description

Operate tactical radio equipment and maintain communication networks in field environments. Provide communication support to combat units.

A Day in the Life

You start by drawing and checking your radios, antennas, and crypto gear before establishing the net. The day is spent operating tactical radios, maintaining communications for the units you support, and troubleshooting when a station drops out. You often work from a vehicle or a hasty position in the field, monitoring nets and passing traffic for hours on end.

Current Mil Compensation & Long-Term Benefits (FY 2026)

Every MilCareer below is paid using the same base structure: Base Pay + tax-free BAH + tax-free BAS + bonuses — plus retirement, health, and education benefits that follow you for life. The per-MOS estimates farther down combine projected lifetime compensation including these allowances.

FY 2026 Base Pay

3.8% across-the-board active-duty pay raise effective Jan 1, 2026 (on top of the targeted 10% junior-enlisted raise from Apr 2025). E-1 base $2,407/mo ≈ $28,886/yr; E-5 with 6 yrs $4,300/mo ≈ $51,599/yr; O-1 with <2 yrs $4,150/mo ≈ $49,802/yr; O-3 with 6 yrs $8,126/mo ≈ $97,506/yr.

BAH (Housing Allowance)

Tax-free, varies by ZIP, rank, and dependents. 2026 rates effective Jan 1, 2026 — average 4.2% increase over 2025 (example: E-5 with dependents in Norfolk ≈ $2,430/mo). Rate protection applies: if your area's rate drops, you keep your current amount while stationed there.

BAS (Subsistence)

Tax-free monthly food allowance. 2026 rates: enlisted $476.95/mo ($5,723/yr); officers $328.48/mo ($3,942/yr).

BRS Retirement & TSP Match

Blended Retirement System (all members joining 2018+). DoD auto-contributes 1% of base pay to your Thrift Savings Plan (TSP) and matches up to an additional 4% — a 5% guaranteed return. Vest at 2 years, fully portable if you separate before 20.

20-Year Pension (Lifetime)

BRS multiplier: 2.0% × years × average of highest 36 months base pay (paid for life starting at retirement). 20-year E-7 ≈ $25K–$28K/yr; 20-year O-5 ≈ $55K–$65K/yr. Optional lump-sum (25% or 50%) at retirement, plus continued TRICARE.

TRICARE Health Care

$0 premium for active-duty members and their families (TRICARE Prime). Retirees pay modest enrollment fees — 2026 TRICARE Prime: $381.96/yr individual / $765/yr family (Group A); $462.96 / $927 (Group B, joined 2018+). Dental and vision available.

Post-9/11 GI Bill

After 36 months active duty: 100% in-state public tuition + monthly housing stipend (BAH at the school's ZIP) + $1,000/yr book stipend, for 36 months. Transferable to spouse/children after 6 years of service. Yellow Ribbon covers gaps at private/out-of-state schools.

VA Benefits (Lifetime)

Service-connected disability comp is tax-free, monthly, for life — 2026 rates (2.8% COLA, effective Dec 1, 2025): 10% = $180.42/mo, 50% = $1,132.90/mo, 100% = $3,938.58/mo (single, no deps). VA home loan with $0 down/no PMI, VR&E (Chapter 31), VA health care, life insurance (VGLI), and PACT Act expanded toxic-exposure care.

Projected Compensation for This MOS

Estimated total compensation (base pay + BAH + BAS + benefits + bonuses typical for this MOS) at common career milestones. Actual pay depends on rank progression, location, dependents, and bonuses earned.
